3y is 45% of what number

Mathematics
1 answer:
alexdok [17]2 years ago
6 0

Answer:

Call the number x and y. Then:

x - y = 45

and

x/y = 4, So x = 4y

Substitute 4y for x in the first equation:

4y - y = 45

3y = 45

y = 45/3 = 15

Substitute y = 15 in the first equation

x - 15 = 45

x = 45 + 15 = 60

So the two numbers are 60 and 15

Step-by-step explanation:

hope this helps

Given ZW=20. Answer the questions please. ​
djyliett [7]

a) Corresponding angles of similar figures are congruent, so \angle B \cong \boxed{\angle Z}

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is \frac{25}{10}=\boxed{5/2}

c) Since the scale factor is 5/2,

\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}
