Answer:
35
Step-by-step explanation:
2x = 2 times 4.5
= 9
5y = 5 times 5.2
= 26
2x + 5y is 9 + 26
= 35
35
Steps
2x + 5y
x = 4.5
y = 5.2
a. Substitute
2(4.5) + 5(5.2)
b. Multiply
9 + 26
c. Add
35
Therefore, the answer is 35.

How many solutions does the following equation have ?
- 32 +9 – 2x = -12 – 5x
Choose 1 answer:
No solutions
B
Exactly one solution
С
Infinitely many solutions
Answer:Exactly one solution.
Step-by-step explanation:
- 32 +9 – 2x = -12 – 5x
1.Add numbers
-23 - 2x= -12-5x
2.Rearrange terms
-2x - 23 = -12 - 5x
3. Rearrange terms
-2x - 23 = -5x-12
4. Add 23 to both sides of the equation
-2x-23+23= -5x-12+23
5.Simplify
-2x= -5x+11
6.Add 5x to both sides of the equation
-2x+5x=-5x+11+5x
7.Simplify
3x=11
8.Divide both sides of the equation by the same factor
[tex]\frac{3x}{3}[/tex] = [tex]\frac{11}{3}[/tex]

Candice leaves on a trip driving at 25 miles per hour. Four hours later, her sister Liz starts from the same location driving at 50 miles per hour. How long after Liz leaves home will she catch up to Candice?
9 hours
4 hours
7 hours
8 hours
Answer:
The time that Liz will take to catch up with Candice after Liz starts is:
4 hours.Step-by-step explanation:
We're gonna use the formula:
Distance = Speed * TimeAnd we'll give a variable for each driven distance:
C= Candice's driven distance. L= Liz's driven distance.Now, Liz begins when four hours had passed, then, from the beginning of this exercise Candice's distance is:
25 miles / hour * 4 hours = 100 milesCandice had a 100 miles lead when Liz started, so, the distances 1 hour after Liz began were:
C= 25 miles / hour * 1 hour + 100 miles = 125 miles. L= 50 miles / hour * 1 hour = 50 miles.When two hours have passed:
C= 25 miles / hour * 2 hour + 100 miles = 150 miles. L= 50 miles / hour * 2 hour = 100 miles.When three hours have passed:
C= 25 miles / hour * 3 hour + 100 miles = 175 miles. L= 50 miles / hour * 3 hour = 150 miles.And, when four hours have passed:
C= 25 miles / hour * 4 hour + 100 miles = 200 miles. L= 50 miles / hour * 4 hour = 200 miles.Then, Liz will catch up with Candice 4 hours after she leaves because after that time the distance traveled is the same for them.

Answer: Mom bought 10 chickens
Step-by-step explanation: if each chicken had 2 wings and there were 20 wings you divide
Answer:
3. Zack has 6 times more seeds than Ben, if Ben has 5 seeds, just multiply how many seeds Ben has by 6, which means Zack planted 30 seeds (This can be written Z=B*6, where Z is how many seeds Zack has, and B is how many seeds Ben has)
1. If there are a total of 40 cards divided into 8 groups of students, that means that each group got 5 card (40 ÷ 8 = 5)
2. If each chicken has 2 wings, and she has a total of 20 wings, that means that she bought a total of 10 chickens (20 ÷ 2 = 10)
What is the equation of a line that passes through the points (–3, 4) and (2, 8)?
Answer:

Jill weighs 15 lbs. Less than Ken. Pete weighs 50 lbs. More than Jill. Eddie weighs 18 lbs. Less than Pete. How much does each weight, if the sum of their weights is 597?
Answer:
Jill = 125lb
Pete = 175lb
Eddie = 157lb
Ken = 140lb
Step-by-step explanation:
Given
Represent Jill with J; Ken with K; Pete with P and Eddie with E
[tex]J = K - 15[/tex]
[tex]P = 50 +J[/tex]
[tex]E = P - 18[/tex]
[tex]J + K + P + E = 597[/tex]
Required
Determine the weight of each
Substitute 50 + J for P in [tex]E = P - 18[/tex]
[tex]E = 50 + J - 18[/tex]
[tex]E = J + 50 - 18[/tex]
[tex]E = J + 32[/tex]
Make K the subject in [tex]J = K - 15[/tex]
[tex]K = J + 15[/tex]
Substitute [tex]K = J + 15[/tex], [tex]E = J + 32[/tex], [tex]P = 50 +J[/tex] in [tex]J + K + P + E = 597[/tex]
[tex]J + J + 15 + 50 + J + J + 32 = 597[/tex]
Collect Like Terms
[tex]J + J +J + J = 597 - 32 - 50 - 15[/tex]
[tex]4J = 500[/tex]
[tex]J = 500/4[/tex]
[tex]J = 125lb[/tex]
Substitute 125 for J in [tex]P = 50 +J[/tex]
[tex]P = 50 + 125[/tex]
[tex]P = 175lb[/tex]
Substitute 175 for P in [tex]E = P - 18[/tex]
[tex]E = 175 - 18[/tex]
[tex]E = 157[/tex]
Substitute 125 for J in [tex]K = J + 15[/tex]
[tex]K = 125 + 15[/tex]
[tex]K = 140[/tex]

The perimeter of a rectangle is 154 cm. The ratio of the length to the width is 10: 1. Find the length and the width
Answer:
length=70cm
width=7cm
Step-by-step explanation:
total ratio=10 + 1
=11
length(2)=10/11 x 154 cm
=10 x 14cm
=140cm
one length is 140 cm/2=70cm
width(2)=1/11 x 154cm
=14cm
one width is 14cm/2=7cm
The length and the width should be considered as the 70 cm and 7 cm.
Calculation of the length and width:Since
The perimeter of a rectangle is 154 cm.
The ratio of the length to the width is 10: 1.
So here total ratio=10 + 1
=11
Now length 2 should be
=10/11 x 154 cm
=10 x 14cm
=140cm
So,
one length is 140 cm/2=70cm
Now
width(2)=1/11 x 154cm
=14cm
And,
one width is 14cm/2=7cm
hence, The length and the width should be considered as the 70 cm and 7 cm.

Answer:
Step-by-step explanation:
3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)
as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm
I'm guessing that it is... soooo distribute the minus sign
= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2
= a^4 -6a^2 -8 :) voila that's your answer

Step-by-step explanation:
A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
Step-by-step explanation:
Volume of Cone
= 1/3 * (Base Area) * (Height).
Since the radius of the cone is r/2, we have
Base Area = π(r/2)² = πr²/4.
Also the height of the cone is r.
Hence Volume of Cone
= 1/3 * (πr²/4) * (r)
= πr³/12. (C)

2x-1/3 -3x/4 =5/6
solve for x
Answer:
x= 14/15
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x−13−3x4=562x+−13+−34x=56(2x+−34x)+(−13)=56
(Combine Like Terms)
54x+−13=5654x+−13=56
Step 2: Add 1/3 to both sides.
54x+−13+13=56+1354x=76
Step 3: Multiply both sides by 4/5.
(45)*(54X)=(45)*(76)x
