Answer:
70
Step-by-step explanation:
is/of = %/100
Change your is to x so you solve for it, so x/50 = 140/100, now cross multiply and it is now 100x = 7000, divide by 100, so x or (is) is 70
Answer:
Step-by-step explanation:
we can do like
8y-7x+2y² -x-5
= 2y^2 + 8y - 8x - 5 ( we know that - 5 = 8 - 13)
= 2( y^2 + 4y + 4) - 8x - 13
= 2 (y+2)^2 -8x - 13
I do not know that you wrongly type but here is the answer.
If 3 is the number missed, we want the percentage wrong
![\frac{10}{100} = \frac{3}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B100%7D%20%3D%20%20%20%5Cfrac%7B3%7D%7Bx%7D%20)
3(100)=10(x)
10x=300
Divide by 10
x=30
The interior angle of a triangle is the angle made by two sides of this triangle and what is the little angle made by these two sides
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
