Answer:
[tex]\boxed{\boxed{\tt m=-13}}[/tex]
Step-by-step explanation:
[tex]\tt 9m-\left(6m-7\right)=2\left(m-3\right)[/tex]
Expand, Apply the Distributive property:
[tex]\tt 9m-\left(6m-7\right)\leadsto \underline{3m+7}[/tex]
[tex]\tt 2\left(m-3\right)\leadsto \underline{2m-6}[/tex]
[tex]\star \:\:\tt 3m+7=2m-6[/tex]
Subtract 7 from both sides:
[tex]\star \:\:\tt 3m+7-7=2m-6-7[/tex]
[tex]\star \:\: \tt 3m=2m-13[/tex]
Subtract 2m from both sides:
[tex]\star \:\: \tt 3m-2m=2m-13-2m[/tex]
[tex]\star \:\: \tt m=-13[/tex]
_____________________________20 people applied for a job. Everyone either has a school certificate or diploma or even both. If 14 have school certificates and 11 diplomas how many have a school certificate only
Given:
Either has a school certificate or diploma or even both = 20 people
Having school certificates = 14
Having diplomas = 11
To find:
The number of people who have a school certificate only.
Solution:
Let A be the set of people who have school certificates and B be the set of people who have diplomas.
According to the given information, we have
[tex]n(A)=14[/tex]
[tex]n(B)=11[/tex]
[tex]n(A\cup B)=20[/tex]
We know that,
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]20=14+11-n(A\cap B)[/tex]
[tex]20=25-n(A\cap B)[/tex]
Subtract both sides by 25.
[tex]20-25=-n(A\cap B)[/tex]
[tex]-5=-n(A\cap B)[/tex]
[tex]5=n(A\cap B)[/tex]
We need to find the number of people who have a school certificate only, i.e. [tex]n(A\cap B')[/tex].
[tex]n(A\cap B')=n(A)-n(A\cap B)[/tex]
[tex]n(A\cap B')=14-5[/tex]
[tex]n(A\cap B')=9[/tex]
Therefore, 9 people have a school certificate only.

“28 is 40% of what number?” i got 70, is that correct?
Answer:
70
You got it correct :)
Step-by-step explanation:
[tex]\frac{28}{y} =\frac{40}{100}[/tex]
y × 40 = 100 × 28
40y = 2800
40y ÷ 40 = 2800 ÷ 40
y = 70
A certain bank offers a car loan with a fixed annual interest rate. Justine applied for the loan and used the entire amount to buy a car worth $43,000. He had to pay the bank for five years for a total amount of $51,600. How much would be the yearly interest if Justine borrowed $50,000 instead? *
0 points
Answer: $10000
Step-by-step explanation:
From the question,
Principal = $43000
Time = 5 years
Rate = Unknown
Simple Interest = $51,600 - $43000 = $8600
We need to calculate the rate of interest which will be:
Interest = PRT/100
8600 = (43000 × 5 × Rate) / 100
Cross multiply
8600 × 100 = 215000 × Rate
Rate = 860000 / 215000
Rate = 4%
Assuming Justine borrowed $50,000 instead, the yearly Interest will be:
= (50000 × 5 × 4%)
= 50000 × 5 × 0.04
= $10000

Find 3[g(4)] if g(x) = -2x + 10
Answer:
6
Step-by-step explanation:
= 3[-2(4) + 10]
= 3(-8 + 10)
= 3(2)
The function is given as g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.
What is a function?A function is a type of relation, or rule, that maps one input to a specific single output.
Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.
They are also called functions of functions.
We have to find 3[g(4)] if g(x) = -2x + 10
3[g(4)] = 3[-2(4) + 10]
3[g(4)] = 3(-8 + 10)
3[g(4)] = 3(2)
3[g(4)] = 6

Can somebody help me with this! Please
Answer:
Step-by-step explanation:
3(x +2 ) = 18 {Use distributive property: a(b +c) =a*b + a*c}
3*x +3*2 = 18
3x + 6 = 18 {Subtract 6 from both sides}
3x = 18- 6
3x = 12 {Divide both sides by 3}
x = 12/3
x = 4

Solve the quadratic equation
(x+2)^2=1
Answer: x = -1, -3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Taking the square root of both sides leads to
x + 2 = ±1
which in turn comes out to x = -2 + 1, or x = -1, and x = -2 - 1, or x = -3
How do I solve for X?
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7

Answer:
∠ X = 80° , ∠ V = 60°
Step-by-step explanation:
(a)
Since XY and WX are congruent then the triangle is isosceles and the 2 base angles are congruent, that is
∠ W = ∠ Y = 50° , so
∠ X = 180° - (50 + 50)° ← sum of angles in triangle
∠ X = 180° - 100° = 80°
(b)
Since the 3 sides are congruent then the triangle is equilateral with the 3 angles congruent, each 60°
∠ V = 60°
