Joshua's math textbook waze 4.21 ounces his social studies book weighs 3.99 ounces what is the difference in weight between the bowl book joshua's math textbook weighs 4.21 ounces his social studies book weighs 3.99 ounces what is the difference in weight between the both books

The given weight of Joshua's math textbook = 4.21 ounce

The given weight of Joshua's social studies textbook = 3.99 ounce

Hence, the difference in weight between the both the textbooks is- subtract the weight of social studies textbook from math textbook, which is:

4.21 - 3.99 = 0.22 ounce

Hence the difference in weights is 0.22 ounce.

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!

150.6

all i did was i multiplied 5.02 by 30
