Question

90/21 + 98% of -98+_7y=155

Step by step directions

Answer 1

90/21 + 98% of -98+_7y=155

If this equation was 90/21 + 98% of -98 + 7y=155, then:

Change 98% to its decimal equivalent, .98.

30/7 + .98(-98) + 7y = 155

Multiply .98(98)

30/7 - 96.04 + 7y = 155

Subtract 30/7 on both sides. Write answer as a fraction.

- 96.04 + 7y = 1055/7

Add 96.04 on both sides. Write answer as a fraction.

7y = 43182/175

Divide by 7.

y = 43182/175 or 35.25061224


If this equation was 90/21 + 98% of -98 + (-7y) =155, then:

Change 98% to its decimal equivalent, .98.
30/7 + .98(-98) - 7y = 155

Multiply .98(98)
30/7 - 96.04 - 7y = 155

Subtract 30/7 on both sides. Write answer as a fraction.
- 96.04 - 7y = 1055/7

Add 96.04 on both sides. Write answer as a fraction.
-7y = 43182/175

Divide by -7.
y = -43182/175 or -35.25061224

I hope this helps!! :-)

Answer 2

If I understand your question right, I think this is what you are looking for:

90/21 + 98% of -98+_7y = 155
90/21 + 98% of: - 98 + 7y = 155
90/21 + 98% of: + 7y = 155 + 98
90/21 + 98% of: + 7y = 253
90/21 + 98% of: + y = 253/7
90/21 + 98% of: + y = 36∙142 857 14...
90/21 + y = 36∙142 857 14...* 98/100
90/21 +( y = 35∙42)
90/21 + 35∙42
4∙285 714 286 + 35∙42
39∙705 714 29
≈ 39∙71

Answer 3

90/21 + 98% of -98+_7y=155
Assuming the _ is for spacing amd maintaining integer form as long as possible,
90/21 - 98*98/100 + 7y = 155
90 - 21*98*98/100 + 147y = 3255
9,000 - 201,684 + 14,700y = 325,500
14,700y = 325,500 - 9,000 + 201,684
14,700y = 518,184
y = 518,184 / 14,700 ≈ 35.25061 ≈ 35.25

Answer 4

==

90/21 +0.98(-98) + 7y = 155 ==

90/21 - 96.04 + 7y = 155 ==

7y = 155 + 96.04 - 90/21 ==

7y = (3255 + 2016.84 - 90)/21 ==

7y = 5181.84/21 ==

y = 5181.84/147

or approximately 35.2506
