Answer:

The correct answer is 12.

Step-by-step explanation:

To solve this problem, we must plug in 3 for each occurrence of y in the expression because we are given that y = 3. In this case, we will get the following:

7y - 3y

7(3) - 3(3)

To evaluate, we must simplify this expression. Due to the order of operations, we should compute the multiplication first. 7*3 = 21 and 3*3=9, so we can plug in these values into our expression.

21 - 9

Now, we can perform the subtraction.

21-9=12

Therefore, the correct answer is 12.

Hope this helps!

Find the GCF of 5y5 and 50y2.

GREYUIT [131]

Answer: $5y^2$

Step-by-step explanation:

Given

$5y^5\ \text{and}\ 50y^2$

GCF or HCF of the two is the highest common factor

$\Rightarrow 5y^5=5\times y^2\times y^3\\\Rightarrow 50y^2=5\times y^2\times 10$

It is clear GCF is $5y^2$

-3s -5=4 what is this problem

Darina [25.2K]

-3s-5=4 First add 5 to both sides of the equal sign to cancel out -5
+5 +5 You're left with -3s=9

-3s=9 Divide by -3 on both sides. This cancels out the -3s. 9 divided by -3 equals -3. The answer would be s=-3

Evaluate the following expression: 62 − 7(8 + 6 − 32)

Alex Ar [27]

Answer:

188

Step-by-step explanation:

Step 1: Distribute

62 − 7(8 + 6 − 32)

62 + (-7 * 8) + (-7 * 6) + (-7 * -32)

62 + (-56) + (-42) + (224)

Step 2: Combine the first two numbers

(62 - 56) - 42 + 224

6 - 42 + 224

Step 3: Combine the next two number

(6 - 42) + 224

-36 + 224

Step 4: Combine the last two number

-36 + 224
