Answer:
1 1/3
Step-by-step explanation:
We simplify it into 3 1/6 - 1 5/6.
Since 5 cannot subtract from 1, we convert 3 1/6 into 2 7/6 because it is equivalent to 3 1/6, and subtract 1 5/6 from that fraction to get 1 1/3.

At Grocery Mart, strawberries cost $2.99 for 2 lb., and at Baldwin Hills Market strawberries are $3.99 for 3 lb.
What is the unit price of strawberries at each grocery store? If necessary, round to the nearest penny.
Grocery Mart:
$_________
Answer:
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33
Step-by-step explanation:
Unit price in this case will be the price divided by number of pounds
Let u1 be the unit price of Grocery Mart and u2 be the unit price at Baldwin Hills
Given
[tex]s_1 = 2.99\\w_1 = 2\\s_2 = 3.99\\w_2 = 3[/tex]
The unit price for Grocery Mart is:
[tex]u_1 = \frac{s_1}{w_1}\\= \frac{2.99}{2}\\= 1.495[/tex]
Rounding off to nearest penny
u1 = $1.50 per lbs
Unit price for Baldwin Hills is:
[tex]u_2 = \frac{s_2}{w_2}\\=\frac{3.99}{3}\\=1.33[/tex]
u2 = $1.33 per lbs
Hence,
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33

The graph represents the speed at which Pete’s marble travels.
The speed of Stephano’s marble is represented by the equation f = 2.25s, where f is the distance in feet and s is the time in seconds.
Whose marble will reach the 6-foot mark sooner?
Answer:
B
Step-by-step explanation:
Here, we simply want to know who will reach the 6-foot mark sooner
Mathematically, we need to get the slope from the graph
Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds
So what this mean is that, in 4 seconds, the 6 ft mark will be reached
This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs
Now compare this with what Stephano has, which is 2.25 ft/ s
we can see that stephano is traveling at a better speed and will reach the 6 ft mark first
So the correct option is B

The thickness of a block is approximately 2 centimeters. How many blocks are in a stack that is 1,000 millimeters high? ( 1 cm = 10 mm ) Use proportions. Help please with explanation thank you!!
Answer:
50 blocks
Step-by-step explanation:
First of all, you need to label you're proportions, which can be mm/blocks.
Then, for 1 block, it is 20 mm because the block is 2 cm, which is equal to 20 mm. So for you're proportion, it is 20 mm/1 block.
Finally, you need to find the total amount of blocks that equals 1000 mm. So you can multiply the 20 mm by 50 to get the 1000 mm. What you do at the top, you do at the bottom, so you also have to do 1 block by 50 to get 50 blocks
So for you're final answer/proportion, it is mm/blocks = 20/1 = 1000/50 and you're final answer is 50 blocks

Solve the following equation by combining like terms:
x +x +2 +3x- 6 = 31
Answer:
x=7
Step-by-step explanation:
We want to get the variable "x" alone to get our answer. So.
1. combine like terms
x+x+2+3x-6=31
like terms in equation: (left side)
x, x, 3x= 5x (equation: x+x+3x)
2, -6= -4 (equation: 2-6)
so, this is what the equation would look like with our new answers:
5x-4=31
2. add 4 to both sides
5x-4+4=31+4
(on left side of equation, the -4 and +4 cancel each other out, leaving the 5x alone)
5x=35
3. divide 5 from both sides, to get the "x" alone
5x/5=35/5
so, our answer would be:
x=7

The sides of a right triangle are (x-5) (x+2) (x+3). solve for x.
Can someone pls help me on this problem
Answer:
x = 10.
Step-by-step explanation:
The longest side , the hypotenuse = x + 3 because the lengths of the sides are positive.
So, by Pythagoras:
(x + 3)^2 = (x - 5)^2 + (x + 2)^2
x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4
0 = 2x^2 - x^2 - 10x + 4x - 6x + 29 - 9
x^2 - 12x + 20 = 0
(x - 10)(x - 2) = 0
x = 2, 10.
x cannot be 2 because that would make one side = 2- 5 = -3 so the answer is x = 10.
Harry buys a TV priced at £1200 plus 20% VAT. He pays £300 deposit and the balance in ten equal monthly payments. Calculate each monthly payment. please explain fully in parts.
Answer:
114 monthly payment
Step-by-step explanation:
1200 + 20%= 1440 (20% of 1200 equals 240)
the VAT has to be added to the purchase price.
1440 is the total price he had to pay for the tv.
he pays 300 down. 1440-300 = 1140
1140 is the remaining balance he had to pay over the next 10 month.
1140 ÷ 10 = 114
divide 1140 by 10 payments and you receive you monthly payment amount. 114

If g + 11 = 16, then evaluate 5g + 12
Answer:
37
Step-by-step explanation:
use inverse operations to solve ,
16 - 11 = g
g = 5
if g = 5 then , 5 times 5 is 25 , add 12 to 25 and get 37
*please name brainliest if you can :)
The value of the expression 5g + 12 is 37, when g equals 5.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Given A equation g + 11 = 16.
g = 16 - 11.
g = 5.
Now, 5g + 12
= 5×5 + 12.
= 25 + 12.
= 37.

The school nurse told Sarah she was 1.4 meters tall. When she got home, Sara measured her height herself. Her measurement included a digit in the hundredths place. That digit had a value that is the value of the digit in the tenths place. How tall did Sara measure herself to be?
Answer:
1.44 meters
Step-by-step explanation:
Given that:
As per the nurse, height of Sarah = 1.4 meters
Let us have a look at the number and let us analyze each digit.
Here is only one digit after the decimal place which is the tenths place.
It is given that Sarah measured the height herself.
And also added a digit at the Hundredth place i.e. a digit after 4 will be added.
1.4_ --- In place of _ , a digit will be added.
As per the question statement, Digit at the Hundredth place will be equal to the digit at the Tenth's place.
Therefore, the height measured by Sarah herself will be equal to 1.44 meters.
