Answer:
c.1
Step-by-step explanation:
5: 15 x:3
a:b c:d The ratios have to stay in proportion. So if we multiply a and b by a certain number they will equal c and d. We just don't know what that number is yet. Call it something.
a* something = c and b* something =d
5 * something = x
15* something = 3
Solve for the unknown number we are multiplying by
Divide each side by 15
15/15 * something =3/15
something = 1/5
Now that we know what we are multiplying by, we can solve for x
So 5 * something = x
5* 1/5 = x
1 =x
Answer:
The answer is B
Step-by-step explanation:
2x+2y =10 and y= -x +5
These are not in the same form so thats the first step
2x+2y=10
we minus 2x from both side which turns into
2y=-2x+10 (the variable always comes first)
Secon step is to divide 2 from the y to everything so 2y divided by 2 = y
-2 divided by 2 is -x and 2 divided by 10 is 5 and now you have the same equations which leads to infinite
y=-x+5

A=1/2.b.h
given Area is 24 and base is 8
24=1/2.8.h
24=4.h (divide 4 both of sides)
h=6 (height)
