How do I solve 2(x+1) + 5(2x-3)=

Mathematics

You multiply 2(x+1) which is 2x+2.

Then you multiply 5(2x-3) which is 10x-15

Finally, you add 2x+2 and 10x-15, and you get 12x-13


The answer is 12x - 13


Hope this helps!

Use the distributive property: multiply the number outside of the parentheses by BOTH numbers inside. 2 × x and 2×1 so first part is 2x+2 second part: 5 × 2x and 5×-3 is 10x-15 so 2x+2+5x-15= 7x-13

Angela and Michelle shared some money in the ratio 4: 9 then Angela gave Daniel half her share.Michelle gave Daniel a third of h
SVEN [57.7K]

Using a system of equations, it is found that £52 was originally shared.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

  • Variable x: Angela's share.
  • Variable y: Michelle's share.
  • Variable z: Daniel's share.

Angela and Michelle shared some money in the ratio 4: 9, hence, considering t as the total:

  • x = \frac{4t}{13}.
  • y = \frac{9t}{13}

Angela gave Daniel half her share.Michelle gave Daniel a third of her share. Daniel was given a total of £20, hence:

\frac{x}{2} + \frac{y}{3} = 20

\frac{4t}{26} + \frac{9t}{39} = 20

\frac{12t + 18t}{78} = 20

30t = 20 x 78

t = 20 x 78/30

t = £52.

3. Martin's car had 86,456 miles on it. Of that distance, Martin's wife drove 24,901
Jet001 [13]

Answer:

Martin Drove about 60,000

Martin Drove exactly 53,558

Step-by-step explanation:

90,000 - (20,000 +10,000) = x

60,000 = x

86,456 - (24,901 - 7,997) = x

53,558 = x
