What is 3d+8=2d-7 is equations

1 answer:

6 0

3d + 8 = 2d - 7 equals d = -15.

First, subtract 2d from both sides. Your problem should look like: 3d + 8 - 2d = -7.
Second, simplify 3d + 8 - 2d to get d + 8. Your problem should look like: d + 8 = -7.
Third, subtract 8 from both sides. Your problem should look like: d = -7 - 8.
Fourth, simplify -7 - 8 to get -15. Your problem should look like: d = -15, which is your answer.

Hopefully this helps, I'm not exactly sure what you meant by "is equations," but this is how you solve the problem.

Naruto ran 634 miles today, and Sakura Ran412 miles. How many times the length of Sakura's distance was Naruto's distance? Selec

Answer:

Step-by-step explanation:

The question reads much more complicatedly than the actual equation.

Sakura * x = Nanuto

412 x = 634 Divide by 412

x = 634/412

x = 1.54 times

The closest answer is 3/2 as far. 1.54 is just about 3/2.

Help please my moms going to kill me if I don’t get this right

Answer:

$x=-\frac{41}{6}$

Step-by-step explanation:

Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation $137+2(-3x+1)=180$ and solve for x:

$137+2(-3x+1)=180$

$137+(-6x+2)=180$

$137-6x+2=180$

$139-6x=180$

$-6x=41$

$x=-\frac{41}{6}$

Answer:

The ceiling is lower than 3 meters.

Step-by-step explanation:

In the above, the product is <em>less than</em> 3. In this case, it will not include 3 as a choice, as if it would, the $\leq$ would be used.

This means that x would be any number that is less than 3. The only choice that gives a choice that means less than by the terms definition is A) The ceiling is lower than 3 meters.

Pierre is running 26 and 2/10 miles in the marathon. He has run 3/4 of the way. How far has he run?

Harman [31]

Pierre ran 19 and 13/20 miles.

Given:
marathon length : 26 2/10 miles
pierre's length ran : 3/4 of the way.

Multiply the fractions.
Convert the marathon length from a mixed fraction into a fraction.
26 2/10 = ((26*10)+2)/10 = (260+2)/10 = 262/10

262/10 * 3/4 = (262*3) / (10*4) = 786/40 = 19 26/40

19 26/40 simplified to 19 13/20 miles

26 ÷ 2 = 13
40 ÷ 2 = 20
