Answer:
8 1
/2
For this we need to determine what
2
/3 of 12 3/4 is, so we multiply the fractions together.
Answer:
x = 16
Step-by-step explanation:
5 = 1/2(x) - 3
Add 3 to both sides.
8 = 1/2(x)
Rewrite for clarity.
1/2(x) = 8
x/2 = 8
Multiply both sides by 2.
x = 16.
Proof:
5 = 1/2(x) - 3
Substitute variable.
5 = 1/2(16) - 3
Multiply 1/2 and 16.
5 = 8 - 3
Subtract 3 from 8.
5 = 5
Answer:
-13
Step-by-step explanation:
5x − 3y − z
substitute x = −2, y = 2, and z = −3
5(-2) -3(2) - (-3)
multiply
-10 -6 +3
-16 +3
-13
When the number is out of parenthesis it means it is multiplying the number between the parenthesis
example - 3 ( 28 + 32 ) => 3 ( 60)
which means 3 * 60 = 180
Note:- you cannot multiply the numbers when they are 3 ( 28 + 32 ) because you have to use PEMDAS ( order of operation ) to solve the problem where P = parenthesis , E = exponents, M = multiplication, D = divide , A = addition , S = subtract.
10/25 and 6/15
10/25=2/5 and 6/15=2/5
Sorry for the mixup.
