The triangle has a base of 7 so 1/2 the base is 3.5.
The height = 7.5 (from graphic)
Area of "left triangle" = 3.5*7.5 / 2 =
<span>
<span>
<span>
13.125
</span>
</span>
</span>
The entire triangle area = 2 * 13.125 =
26.25
Triangle perimeter both legs = 16.6 + base (7) = 23.6
Answer:
[1] 9x - 4y = 7
[2] x - 4y = -17
[2] x = 4y - 17
// Plug this in for variable x in equation [1]
[1] 9•(4y-17) - 4y = 7
[1] 32y = 160
// Solve equation [1] for the variable y
[1] 32y = 160
[1] y = 5
// By now we know this much :
x = 4y-17
y = 5
// Use the y value to solve for x
x = 4(5)-17 = 3

Answer:
<h2>24j - 16 = 8(3j - 2)</h2>
Step-by-step explanation:
The distributive property: <em>a(b - c) = ab - ac</em>
24j - 16 = (8)(3j) - (8)(2) = 8(3j - 2)
If you are asking what to multiply on each side to get rid of 3/5 then you would do B. 5/3 but im not 100% sure if that is what you're asking
Answer:
$91
Step-by-step explanation:
They bought 7 backpacks each costing $8. Multiply them together to get $56. They filled each with $5 worth of supplies. 7 * 5 = 35. $56 + $35 = $91
