Karim (22 years) tells his brother Ziad (8 years).
«l haven't given you a gift for your birthday, but I'll make it up to you. The year when my age will be
triple yours. I'll give you a wonderful gift».
After making his calculations, Ziad tells his brother :
It will cost you nothing». Explain why.
(solve it in an equation of 1 unknown)
Answer:
Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift
Step-by-step explanation:
Equations
Let's make:
x = the number of years from now
Karim now is 22 and Ziad is 8. x years from now Karim will be
22 + x years old and Ziad will be
8 + x years old.
Karim will give Ziad a wonderful gift when:
22 + x = 3(8 + x)
22 + x = 24 + 3x
Solving:
x = -1
This means that Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift

A picture of two horses pulling a carriage to the left.
A free body diagram with 5 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 14,700 N. The second vector is pointing right, labeled F Subscript f Baseline = 75 N. The third vector is pointing upward, labeled F Subscript N Baseline = 14,700 N. The fourth vector is pointing left, labeled F Subscript pi Baseline = negative 1000 N. The fifth vector starts at the tip of the fourth vector, is pointing left, labeled F Subscript p2 Baseline = 800 N. The up and down vectors are the same length. The right vector is shorter than the left vector.
Two horses, Thunder and Misty, are accelerating a wagon 1.3 m/s2. The force of friction is 75 N. Thunder is pulling with a force of 1,000 N, while Misty is pulling with a force of 800 N. The force of gravity is 14,700 N and the normal force is 14,700 N. What is the mass of the wagon? Round the answer to the nearest whole number.

Solve for x
3x - 7 = 2
Answer:
x = 3
Step-by-step explanation:
Add 7 to both the seven and the two and you get 3x = 9. Next, you divide 3 by both sides and get x = 3.
Given the graphs of y = 3x - 1 and y = -2x + 1, determine
which ordered pair is a solution to:
y < 3x - 1
y > - 2x + 1

Identify the two rational numbers.
O A. 1.01
O B. 57
O c.
- 2 /
O D. 1.010010001...
Answer: A. 1.01 Same as 1 1/100 fractions are rational
B. 57 Integers are rational. (Invisible implied denominator is 1)
Step-by-step explanation: c might be, but the denominator is not specified-- or maybe / is supposed to mean square root. So probably not.
D. NO, non-repeating decimal numbers are irrational

The school store sells markers for $0.25 each and pencils for 0.50 each.Anthony spent $ 5.50 to buy a total of 16 markers and pencils. How many markers did Anthony buy?
Answer:
The answer to your question is Antony bought 5 pens
Step-by-step explanation:
pens = p = $0.35
pencils = n = $0.15
total amount = 12
total money spent = $2.80
Process
1.- Write equations
p + n = 12 -------------- (l)
0.35p + 0.15n = 2.80 --------------(ll)
2.- Solve the system of equations by elimination
Multiply equation l by - 0.35
- 0.35p - 0.35n = -4.2
0.35p + 0.15 n = 2.8
0 - 0.2n = -1.4
Solve for n
n = -1.4 / -0.2
n = 7 He bought 7 pencils
3.- Find the value of p
p + 7 = 12
p = 12 - 7
p = 5 He bought 5 pens

Use Heron’s Area Formula to find the value of “x” in the triangle with the given measures. Area = 21.3
[A] x=7.6
[B] x=7
[C] x=8.7
[D] x =5.9
Answer:
the answer is B, x=7

[tex]area = \sqrt{s(s - a)(s - b)(s - c)} [/tex]
please answer i will give you brainiest!!!!!!!!!!!!!!!!!!
Answer:
I'm pretty sure it's A because its showing that the line starts from 1 and goes up if that makes sense.
Answer:
B
Step-by-step explanation:
x < 1 means that x is lesser than 1. A shows x is more than 1 so it is wrong. C shows x is more than -1 which is not entirely true since x could be more than -1, but not less than 1. However, the line in C stretches all the way to 8 which is more than 1 so it is wrong. D shows that x is lesser than -1, but x could have been 0 or -1, so it is not true either.
