Answer:
11
Step-by-step explanation:
So the first thing you do is turn 2 3/4 into an improper fraction by multiplying the mixed number by the denominator and adding the numerator. So the new fraction would be 11/4
Now we multiply 11/4 by the reciprocal of 1/4 which is 4/1
So 11/4 x 4/1 equals numerator x numerator and denominator times denominator so 44/4.
Now we turn that into a mixed number by dividing the numerator by the denominator 44 divided by 4 equals 11
Answer:
x=3
Step-by-step explanation:
Simplifying
4(4x + -3) = 36
Reorder the terms:
4(-3 + 4x) = 36
(-3 * 4 + 4x * 4) = 36
(-12 + 16x) = 36
Solving
-12 + 16x = 36
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + 12 + 16x = 36 + 12
Combine like terms: -12 + 12 = 0
0 + 16x = 36 + 12
16x = 36 + 12
Combine like terms: 36 + 12 = 48
16x = 48
Divide each side by '16'.
x = 3
Simplifying
x = 3
Answer:
f(2.5)=30
Step-by-step explanation:
f(2.5)=6(2.5)+15 plug in 2.5 for x
f(2.5)=15+15 multiply 2.5 by 6
f(2.5)=30 add
Answer:
536
Step-by-step explanation:
To find how many red gumballs where put into the machine: 253-98 = 155
To find how many blue gumballs where put into the machine: 155- 27 = 128
To then find the total amont of gumballs placed into the machine:
253+155+128 = 536 gumballs where placed into the machine in total
x = 3/2
Getting x on one side of the equation:
(2/5)x = 9/15
x = (9/15)(5/2)
x = 9/6
x = 3/2
