Multiply the bracket by 2

(2)(y)=2y

(2)(6)=12

2y+12+3y

2y+3y+12 ( combine like terms)

ROUND 258,177 TO THE NEAREST HUNDRED THOUSAND

Galina-37 [17]

258,177 to the NEAREST HUNDRED THOUSAND is 258,000 and nothing else...

If this number was 275,550, the NEAREST HUNDRED THOUSAND would've been 276,000 because of the last three digits in this number...

Alice is saving money at a constant rate. Suppose she initially has $70 saved, and after 2 months, she has $170 saved.

timofeeve [1]

Answer:

50 dollars per month

Step-by-step explanation:

Given

$Months = 2$

$Total = 170$

$Initial = 70$

Required

Determine the rate of savings

Suppose in a month, she saves x amount.

In 2 months, she would save 2x

When 2x is added to the initial savings, it gives the total amount saved.

So, we have:

$2x + 70 = 170$

Collect Like Terms

$2x = 170 - 70$

$2x = 100$

Divide both sides by 2

$x = \frac{100}{2}$

$x = 50$

<em>Hence, she saves $50 dollars monthly</em>

What values of a and b make the equation true? StartRoot 648 EndRoot = StartRoot 2 Superscript a Baseline times 3 Superscript b

kramer

Option C: $a=3, b=4$ is the value of a and b

Explanation:

Given that the expression $\sqrt{648}=\sqrt{2^a\times3^b}$

We need to determine the value of a and b

Let us consider the term $\sqrt{648}$ and take the prime factorization of the term 648

Thus, we have,

648 divides by 2,

$648=2 \cdot 324$

324 divides by 2,

$648=2 \cdot 2 \cdot 162$

162 divides by 2,

$648=2 \cdot 2 \cdot 2 \cdot 81$

81 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 27$

27 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 9$

9 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 3 \cdot 3$

Thus, we have,

$\sqrt{648}=\sqrt{2^{3} \cdot 3^{4}}$

Therefore, equating the powers of 2 and 3, we get,

$a=3, b=4$

Hence, the value of a and b is 3 and 4

Thus, Option C is the correct answer.
