Ted added parentheses to this expression so that it's value is greater than 75. Where did Ted add the parentheses? 10+9x3-1x2

He added the parenthesis to (10+9)

Step-by-step explanation:

The goal here is to find a part of this expression where we can add parentesis so that the value of the equation would be greater than 75

10+9x3-1x2

When we add parentesis to (10+9), we have:

(10+9)x3-1x2

19x3-1x2

= 112

112 is greater than 75.

If we add the parentheses elsewhere like (9x3)

10+(9x3)-1x2

The value would be

10+37-1x2 = 72

And 72 is less than 75

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
