<u>x = 9</u>
Step-by-step explanation:
mean = 5+7+7+x /4 = 7
19+x / 4 = 7
19+x = 28
x = 9
-1/2 + 2 = 1.5
because if u add 2 to a minus half it goes 0 and then 1.5 (positive half)
Answer:
A
Step-by-step explanation:
area of triangle = 1/2*base*height
small triangle = 1/2*4*3 = 6
Big triangle = 1/2*8*6= 24
24/6=4
the big triangle is 4 times the size of the big triangle. so the small triangle would be 1/4 the size. hence D1/4(xyz) answer is A
Given a right triangle with the side lengths of legs = 9 and 13
For the required angle :
opposite side = 9
adjacent side = 13
so,
Answer:
y = 3x + 3
Step-by-step explanation:
when you check, only that equation delivers the correct x and y pairs.
x = 0, => y = 3×0 + 3 = 3
x = 1, y = 3×1 + 3 = 3+3 = 6
x = 2, y = 3×2 + 3 = 6 + 3 = 9
x = 3, y = 3×3 + 3 = 9 + 3 = 12
it all fits.
