Answer 1

Answer:

A = 3.4

Step-by-step explanation:

235 = 7(4 + 6a) - 3

you're trying to make both sides equal, that means whatever is happening on one side must happen on the other. to take minus 3 out of the equation you add 3 to both sides

235 + 3 = 7(4 + 6a) -3 + 3

238 = 7(4 + 6a)

next add within the parenthesis and multiply that by 7

238 = 7(4 + 6a)

238 = 7 × 10a

238 = 70a

next divide both sides by 70

238 ÷ 70 = 70a ÷ 70

3.4 = a

Answer 2

Answer: For #5, a = 5

Step-by-step explanation:

First, let's open the parenthesis.

235 = 7 (4 + 6a) - 3

235 = 28 + 42a - 3

Next, subtract 28 by 3 on the right side.

235 = 28 + 42a - 3

235 = 25 + 42a

Then, we'll subtract both sides by 25.

235 - 25 = 25 - 25 + 42a

210 = 42a

Finally, let's divide both sides by 42!

210 / 42 = 42a/42

5 = a

So, a = 5.

If Alfonso has a $10 bill. At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas. He gets $5.13 in change. The price of one banana is $0.32

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Alfonso has a $10 bill.

At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas

So $10.00-$1.99= $8.01

We need to find price of one banana.

He gets $5.13 in change.

$8.01-$5.13=$2.88

He used $2.88 to buy nine bananas

The price of each banana we will calculate by dividing $2.88 by 9.

$2.88/9=$0.32

The price of each banana is $0.32, Option A is correct.

if i’m understanding this correctly, your equation would be 2(n-1) -1. n being the first number you are plugging in, which begins with 10.
10, 17, 31, 59, 115

The first five numbers in the sequence are 10, 19, 37, 73 and 145.

What are sequences?

Sequences are a list of elements (numbers, most of the time) in which the order of elements matters.

Given that, The pattern rule for a sequence is "Start at 10, double the number before this one, and subtract 1."

Forming the equation according to question, we get,

(2n-1)

The first number is 10

2nd = 10x2-1 = 19

3rd = 19x2-1 = 37

4th = 37x2-1 = 73

5th = 73x2-1 = 145

Hence, The first five numbers in the sequence are 10, 19, 37, 73 and 145.

to find 10% you need to divide by 10
10% = 3.5
20% = 7
35-7 = 28
I didn’t understand the question I thought it could be one of these two
So if you’re taking off 20% it’s
10%of 35=3.50
3.5 x 2=7
35-7=28

If you’re trying add back on 20%

Which value of b makes the equation b4=12 true? A.48 B.16 C.8 D.3

Answers

the answer is D. 3
3 x 4 = 12

The value of b that makes the equation b * 4 = 12 true is b = 3. Thus, the correct answer is option (D).

Let's apply each option and see which value of b makes the equation b * 4 = 12 true:

A) b = 48

48 * 4 = 192 (not equal to 12)

B) b = 16

16 * 4 = 64 (not equal to 12)

C) b = 8

8 * 4 = 32 (not equal to 12)

D) b = 3

3 * 4 = 12 (equal to 12)

Therefore, the value of b that makes the equation b * 4 = 12 true is b = 3.

Thus, the correct answer is option (D).
