Answer:

4x - 3

Step-by-step explanation:

(7x - 2) - (3x - 5)

Open the bracket and observe the signs,

7x -2 - 3x + 5 ( when the minus outside the bracket multiplies minus in the bracket, it becomes plus)

Collect like terms

7x - 3x - 2 + 5

4x - 3

Answer:

4x + 3 is the answer obtained when we subtract (7x-2) - (3x-5)

Step-by-step explanation:

Given that, (7x-2)-(3x-5)

Minuend = 7x-2

Subtrahend = 3x-5

In subtraction of algebraic terms, we place the variables together and the constants together and then perform the operation

Thus,

= (7x-2)-(3x+5) opening brackets and rewrite the equation.

= 7x-2-3x+5 bring 'x' terms together

= (7x-3x)-(2-5)

= 4x-(-3)

= 4x+3

Thus, after subtracting (7x-2)-(3x-5) we get 4x+3

ANSWER

The correct answer is C

EXPLANATION

We want to find the quotient:

$- \frac{10}{19} \div ( - \frac{5}{7} )$

We multiply by the reciprocal of the second fraction:

$- \frac{10}{19} \times ( - \frac{7}{5} )$

We cancel out the common factors to obtain:

$- \frac{2}{19} \times ( - \frac{7}{1} )$

We multiply to get

$\frac{ - 2 \times - 7}{19 \times 1}$

This simplifies to :

$\frac{14}{19}$

The correct answer is C

Answer: I believe the answer is 0.1875. Must be a typo here, because...

Step-by-step explanation: parentheses first. (2+1)3%32=

After parentheses are taken out. 3x3%32= No exponents, so multiply or divide, whatever comes first.

6%32 is 0.1875

Kristen and Mitchell were given the same math assignment. Kristen completes 0.8 of her work in class. Mitchell completes 0.75 of

monitta

Mitchell because if you add a zero at the end of the .8 it would be 0.80 and 0.75 is smaller than 0.80 so Mitchell has more work to do at home
