Helena needs 3.5 cups of flour per loaf of bread and 2.5 cups of flour per batch of muffins. She also needs 0.75 cup of sugar pe
vesna_86 [32]
Let
 x = loaves of bread
 y = batches of muffins
 You must make a system of two equations with two unknowns that describe the problem
 3.5x + 2.5y = 17 --- (1)
 0.75x + 0.75y = 4.5 --- (2)
 Resolving we have
 x = 6-y (from (2))
 replacing in (1)
 3.5 (6-y) + 2.5y = 17
 21 - 3.5y + 2.5y = 17
 y = 21-17 = 4
 Then substituting in (2)
 x = 6-y = 6-4 = 2
 Answer
 Helena could bake:
 2 loaves of bread
 4 batches of muffins

There are 75 boys in the sixth grade. The ratio of girls to boys is 7 to 5. How many girls are there in sixth grade?
kolbaska11 [484]
There are 105 in 6th grade because there are 75 boys right? So it said the ratio of girls is 7 and the ratio of boys is 5 so I divided 75 to 5 = 15 and I multiply 7 to 15 and got 105 girls.

alexandr1967 [171]

Answer:

2x-64<108

One solution was found :

x < 86

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

2*x-64-(108)<0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

2x - 172 = 2 • (x - 86)

Equation at the end of step 1 :

Step 2 :

2.1 Divide both sides by 2

Solve Basic Inequality :

2.2 Add 86 to both sides

x < 86
