Answer:
w = 24
Step-by-step explanation:
[tex]\frac{5w}{8}[/tex] = 15
Multiply both sides by 8.
5w = 15 × 8
= 120

Marley used 7 cups of water to make 4 loaves of French bread. What equation can be used to model the total cups of water needed y for making x loaves of French bread? Write the equation in the form y =kx .
Answer:
[tex]\displaystyle y=\frac{7}{4}.x[/tex]
Step-by-step explanation:
Proportional Relationship
It's the type of relationships between two variables where their ratios are equivalent.
In a proportional relationship, one variable is always a constant value by the other. That constant is known as the constant of proportionality.
A proportional relationship between the variables x and y is written as:
y=k.x
For this problem, y represents the cups of water needed for making x loaves of French bread.
We know Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation:
7=k.4
Solving for k:
[tex]\displaystyle k=\frac{7}{4}[/tex]
The equation to model the problem is:
[tex]\mathbf{\displaystyle y=\frac{7}{4}.x}[/tex]

Rob sells electronics and earns $625 per week, plus 12% of his sales. Last week, he sold $3250 worth of electronics. What was his total earnings for last week?
Answer:
$1,015
Step-by-step explanation:
Given that:
Weekly earning = $625
Commission = 12% of sales
sales made last week = $3250
Last week earning = weekly earning + commision on sale
Commission on sale = 12% of sales
Commission on sale = (0.12 * 3250) = $390
Last week earning = weekly earning + commision on sale
Last week earning = $625 + $390 = $1,015

Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06
What is the area of △MNP?
A. 40 m2
B. 60 m2
C. 68 m2
D. 127.5 m2
answer is B. 60 m2
Step-by-step explanation:
17²=15²+MP²
289=225+MP²
289-225=64
So... MP²=64.... MP=8
8×15= 120
120÷2=60
Eight bottles of soda and four bags of chips cost $16. Six bottles of soda and 7 bags of chips cost $14. How much does a bottle of soda cost? How much does a bag of chips cost?
Answer: soda 1.75 dollars and chips is 0.50 dollars
Step-by-step explanation:you have to work out the question like a simultaneous equation so key s=soda and c=chips
8s+4c=16
6s+7c=14 make chips equal
56s+28c=112
24s+28c=56 Take the equations away
32s=56
S=56\32
S=7/4
S=1.75 sub that answer in the first equation
8*1.75=14
14+4c=16
4c=2
C=0.5

A local school donated canned goods to help the community. Cans were packed into boxes each weighing 16.4 pounds. The volunteers packed 9 boxes. How many total pounds of food did they collect? A. 97.6 B. 147.6 C. 976 D. 1,476
Answer:
147.6 pounds of foodStep-by-step explanation:
Each box weighed 16.4pounds, if the volunteers packed 9 boxes, we need to calculate the total pounds of food collected. Using the equality postulate;
1 box = 16.4 pounds
9 boxes = x pounds of food
Cross multiply;
1 * x = 9 * 16.4
x = 147.6 pounds of food
Hence the volunteers collected 147.6 total pounds of food
