Answer: Fran's number is 70
Step-by-step explanation:
Let x represent Jen's number.
Let y represent Carrie's number.
Let z represent Fran's number.
When you add their numbers together you get 207. This means that
x + y + z = 207 - - - - - - - - - -1
Jen's number is 9 more than Carrie's number. It means that
y = x - 9
Fran's number is 3 less than Jen's number. It means that
z = x - 3
Substituting y = x - 9 and z = x - 3 into equation 1, it becomes.
x + x - 9 + x - 3 = 207
3x - 12 = 207
3x = 207 + 12 = 219
x = 219/3 = 73
y = x - 9 = 73 - 9
y = 64
z = x - 3 = 73 - 3
z = 70
x = 16 in the following equations:
8 × 2 = x
8 + 8 = x
4 × 4 = x
In the following equations, x = 16:
2x = 32
<em>32 ÷ 2 = x = 16
</em>x + 5 = 21
<em>21 - 5 = x = 16</em>
Answer:
28ft^2
Step-by-step explanation:
you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)
if we plug the numbers we are given into the formula we find
1/2(7x8)
1/2(56)
28
we find that the area of this triangle is 28ft^2
