Answer:

A is one of the true statements because 25 is the largest number that 50 and 75 can both divide evenly into.

D is the other true statement because 45 is the lowest number that 5 and 9 can both multiply into.

terry opened a savings account in December with $132 and saved $27 each month beginning in January the value of terrys account i

liq [111]

Let S be the amount in a savings account.
Let m be the number of months.

General equation
S = 132 + 27m

Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321

Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.

3/7•d=9/14 in this Problem you want to find what d equals

sertanlavr [38]

→ Chapter : Fractions ←
≡ We know that:
⇔ $(\frac{a}{b}) \div (\frac{c}{d})=(\frac{a}{b}) \times (\frac{d}{c})$

≡ Solution:
⇒ $(\frac{3}{7}) \times (d)=\frac{9}{14}$
⇒ $d=(\frac{9}{14}) \div (\frac{3}{7})$
⇒ $d=(\frac{9}{14}) \times (\frac{7}{3})$
∴ $\boxed{\frac{3}{2}}$

A, B , and C are collinear points: B is between A and C. If AB = 36, BC = 5x - 9 , and AC = 54 , find x

balandron [24]

Answer:

x = 5.4

Step-by-step explanation:

The segment sum theorem tells you ...

AB +BC = AC

36 +(5x -9) = 54

5x = 27 . . . . . . . . . . . subtract 27 from both sides

x = 5.4 . . . . . . . . . . divide by 5
