Zac is 18 years old.
The ratio of Zac's age to Ed's age is 2:1.
Tim's age is 2/3 Zac's age.
How old is Tim?
Answer:
Tim is 12 years
Step-by-step explanation:
Given that Zac is 18 years old and Tim's age is 2/3 Zac's age, to compute Tim's age, we would multiply Zac's age with the fraction.
Such that;
Tim's age = 2/3 * 18
= 2* 18/3
= 2 * 6
= 12 years
Hence Tim is 12 years old.
Find the number that makes the ratio equivalent to 2:7.

A trapezoid has a base 1 = 6 base = 8 and a height = 3 whats the area?
Answer:
[tex]area = 21[/tex]
Step-by-step explanation:
Area of trapezoid formula:
[tex]area = \frac{a + b}{2} h[/tex]
Given information:
a: 6
b: 8
h: 3
Using the given information,
[tex]area = \frac{6 + 8}{2} 3[/tex]
Add the numbers in the numerator
[tex]area = \frac{14}{2} 3[/tex]
Reduce fraction with 2
[tex]area = 7 \times 3[/tex]
Answer:
[tex]area = 21[/tex]

The function is linear.
The equation of the function is y = - x.
4x+3y=2
2x+y=6
substitution
Answer:
(8,-10)
Step-by-step explanation:
4x+3y=2
2x+y=6--->y=-2x+6
4x+3(-2x+6)=2
4x-6x+18=2
-2x=-16
x=8
4(8)+3y=2
32+3y=2
3y=-30
y=-10
Answer:
x=8 y=-26/3
Step-by-step explanation:
2x+y=6
2x=6-y
2x-6=-y
-2x+6=y
4x+3(-2x+6)=2
4x-6x+18=2
4x-6x+16=0
-2x+16=0
-2(x-8)=0
x-8=0
x=8
4(8)+3y=6
32+3y=6
26+3y=0
3y=-26
y=-26/3
