Answer:

b=12

Step-by-step explanation:

1/2 (b - 10) + 2b = 25

Multiply each side by 2 to get rid of the fractions

2*1/2 (b - 10) +2* 2b = 25*2

b-10 +4b = 50

Combine like terms

5b -10 = 50

Add 10 to each side

5b -10+10 = 50+10

5b = 60

Divide by 5

5b/5 = 60/5

b = 12

Answer:

the answer is 12

Step-by-step explanation:

Simplify both sides of the equation.

12(b−10)+2b=25

(12)(b)+(12)(−10)+2b=25(Distribute)

12b+−5+2b=25

(12b+2b)+(−5)=25 (Combine Like Terms)

52b+−5=25

52b−5=25

add 5 to both sides.

52b−5+5=25+5

52b=30

multiply both sides by 2/5.

(25)*(52b)=(25)*(30)

b=12

The measures of two complementary angles have a ratio of 1:2 what is the measure of each angle
mamaluj [8]

The two angles are 30 degrees and 60 degrees

<em><u>Solution:</u></em>

Given that,

The measures of two complementary angles have a ratio of 1 : 2

Let the one of angle be 1x

Let the other angle be 2x

We know that,

Sum of two complementary angles is 90 degrees

Therefore,

1x + 2x = 90

3x = 90

Divide both sides by 3

x = 30

<em><u>Therefore, measure of each angles is:</u></em>

One angle = 1x = 30

Other angle = 2x = 2(30) = 60

Thus the two angles are 30 degrees and 60 degrees

What number should be placed in the box to help complete the division calculation? can someone please do the problem (8587/12) s
disa [49]

Answer:

8587 should be in the box

Step-by-step explanation:

we would see it question as:       12/- 8587

12 goes into 85  7 times, so 7

12 goes into 18 1 time, so 1

12 goes into 67 5 times, so 5

then the remainder is 7

or you further divide to get . 5 8 3333333...

so your answer should be 715r7 or 715.58333
