You are trying to pack for an overseas trip you have a weight limit for your checked bag and need to know how much everything weighs in order to help narrow things down. you are bringing shoes (s), regular clothes (r), and coats (c), and the expression 2.5s + r+ 3c+ 5 represents the total weight. In pounds, of your packed suitcase. SO if you bring 2 pairs of shoes, 10 items or regular clothes, and 2 coats, how much will your bag weigh?

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
