I need to know the rate in witch they use the toothpaste
Answer:
x = 1
Step-by-step explanation:
Simplifying
7(x + 1) + -2 = 5(x + 1) + 2
Reorder the terms:
7(1 + x) + -2 = 5(x + 1) + 2
(1 * 7 + x * 7) + -2 = 5(x + 1) + 2
(7 + 7x) + -2 = 5(x + 1) + 2
Reorder the terms:
7 + -2 + 7x = 5(x + 1) + 2
Combine like terms: 7 + -2 = 5
5 + 7x = 5(x + 1) + 2
Reorder the terms:
5 + 7x = 5(1 + x) + 2
5 + 7x = (1 * 5 + x * 5) + 2
5 + 7x = (5 + 5x) + 2
Reorder the terms:
5 + 7x = 5 + 2 + 5x
Combine like terms: 5 + 2 = 7
5 + 7x = 7 + 5x
Solving
5 + 7x = 7 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
5 + 7x + -5x = 7 + 5x + -5x
Combine like terms: 7x + -5x = 2x
5 + 2x = 7 + 5x + -5x
Combine like terms: 5x + -5x = 0
5 + 2x = 7 + 0
5 + 2x = 7
Add '-5' to each side of the equation.
5 + -5 + 2x = 7 + -5
Combine like terms: 5 + -5 = 0
0 + 2x = 7 + -5
2x = 7 + -5
Combine like terms: 7 + -5 = 2
2x = 2
Divide each side by '2'.
x = 1
Simplifying
x = 1
F would be wrong because if the oldest was 22, it would an outlier, not 26 and 25.
1. The total shaded area must be 2/8 = 1/4 of the whole area.2.He will need 6 tenth size strips to have an equivalent of 3/5.3.320 (40*8)
4.divide the total number of cards by the total number of persons;
total number of cards: 1,200
total number of persons: 4 (3 friends and Maria)
1,200 ÷ 4 = 300
so each person will get 300 cards.
5. so, there are six groups of 3 students each. This means that there are 18 students in total.
Each of these students sells the same about of balloons: so we can divide the total number of sold balloons; 162 by 18:
which means that each student sold 9 balloons!!
6. Jordan because 21÷3=7<span>

Answer:
C: 77 miles
Step-by-step explanation:
The points form a right triangle triangle with the legs being 44 and 63 and the distance between Washington and Midland being the hypotenuse.
See graph and connect the dots.
We can use the Pythagorean theorem to find the hypotenuse
a^2 +b^2 =c^2
44^2 + 63^2 = c^2
1936 + 3969 = c^2
5905 = c^2
Take the square root of each side
76.84399781
Rounding to the nearest mile
77 miles
