Answer:
y=6.7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
y+4=10.7
Step 2: Subtract 4 from both sides.
y+4−4=10.7−4
y=6.7
Answer: The subtraction property of equality or move the 4 to the other side using subtraction.

One pizza is $12 and a cake is $18. If Matt has $84, how many pizzas can he buy at most and still afford to buy a cake
Answer:
5 pizzas
Step-by-step explanation:
So first you subtract 18 so that you know that there is at least one cake.
84 - 18 = 66
When you get 66 dollars remaining, you divide it by 12 to see how many you can afford.
66/12 = 5.5
So because you can’t say you have an additonal amount of money, you would actually round down to 5.
So Matt can buy a total of 5 pizzas and 1 cake.
Answer:
5
Step-by-step explanation:
To find the number of pizzas Matt can buy while still being able to afford a cake set up an inequality. The inequality should look like [tex]84\geq 12x+18[/tex] where x is the number of pizzas Matt bought. Then, solve the inequality by first subtracting 18 from both sides, [tex]66\geq 12x[/tex]. Next, divide both sides by 12, [tex]5.5\geq x[/tex]. This means that Matt can buy 5 pizzas. At first, it might seem like you should round up; however, if you rounded up at all then Matt could not afford the cake, so you must round down.

A(x) = x * (x + 3)
= x^2 + 3x
A(4) = 4^2 + 3(4)
= 16 + 12
= 28

Amy plans to spend 1/4 of his next month's income on
rent, 1/12 on transportation, 1/6 on food, $590 on other
expenses, and save $925. How much does he plan to
spend on food?
9514 1404 393
Answer:
$505
Step-by-step explanation:
Assuming the listed expenses comprise all of Amy's income (x), we have ...
(1/4)x +(1/12)x +(1/6)x + 590 +925 = x
1515 = 1/2x . . . . . . subtract 1/2x
We note that 1/6x is for food. That amount is 1/3 of 1/2x, so the amount spent on food is ...
(1/6)x = (1/3)(1/2x) = (1/3)(1515) = 505
Amy plans to spend $505 on food.
Answer:
the answer is $505

Use substitution to solve the system of
equations: 5x + 5y = -30
2x - y = 15
Answer:
x = 3, y = - 9
Step-by-step explanation:
5x + 5y = - 30...... (1)
2x - y = 15
-y = 15 - 2x
y = 2x - 15..... (2)
From equations (1) & (2)
5x + 5(2x - 15) = - 30
5x + 10x - 75 = - 30
15x = 75 - 30
15x = 45
x = 45/15
x = 3
Plug x = 3 in equation (2)
y = 2*3 - 15
y = 6 - 15
y = - 9
Therefore,
x = 3, y = - 9
or
(x, y) = (3, - 9)

The side JL is obtained by,x=5
JL=5x+7
JL=5×(5)+7
JL=32
The side ST is obtained
ST=(1/2)×JL
ST= 1/2 of 32
ST = 16
Hence, the length of midsegment ST will be 16.

A passenger train leaves a railway station at 12:00 pm and travels 3 hours on the Northbound track. A second passenger train leaves the same railway station at 12:45 pm and travels 2 hour and 15 minutes on the Southbound tracks at a speed of 20 kilometers per hour faster than the first train. At 3:00 pm the two trains were 360 kilometers apart. How fast was each train traveling?
Answer:
63 kilometers per hour for train A and 83 kilometers for train B
Step-by-step explanation:
Same beginning
Train A: 3 hours to NorthTrain B: 2 hours and 15 minutes to Southbut train B 20 kilometers per hour faster
15 minutes from 20 kilometers per hours are 5 kilometers
So, train B is 45 kilometers travel more far than train B.
= 360 kilometers - 45 kilometers
= 315 kilometers ÷ 5 hours
= 63 kilometers per hours

Find the x-intercept and y-intercept for the following equation. Please show all work 4x-3y=24
Answer:
(6,0) and (0,-8)
Step-by-step explanation:
Substitute a zero for each variable
So 4(0) - 3y = 24 to find the y-int so -3y = 24, y = -8, so y-int is (0,-8)
to find x-int y = 0 so 4x - 3(0) =24 so 4x = 24, so x = 6 so x-int is (6,0)

The measure of angle A is 86.
What is a kite?A kite is a flying object that is tethered to the ground by a string or a cord. It typically has a light framework of bamboo, plastic, or other materials, covered with paper or fabric, and often in the shape of a diamond or triangle.
We have,
From the figure,
We see that,
6x + 4 + ∠A = 180
Now,
∠A = 4x + 26
So,
6x + 4 + 4x + 26 = 180
10x + 30 = 180
10x = 180 - 30
10x = 150
x = 15
Now,
∠A = 4x + 26 = 4 x 15 + 26 = 60 + 26 = 86

Two methods are proposed to measure the effectiveness of a brand of sunscreen.
Method A: Survey adults visiting a beach on a busy weekend. Ask each adult which brand of sunscreen they are using, and assess their arms for sun exposure.
Method B: Volunteers are randomly assigned to one of two brands of sunscreen. Each volunteer is asked to report back at the end of the day, and their arms are assessed for sun exposure.
Which statement is a correct interpretation of these methods?
Both methods are experiments because sun exposure is assessed in both methods.
Both methods are observational studies because neither method attempts to influence responses.
Method A is an experiment because it compares many brands of sunscreen, while method B is an observational study.
Method B is an experiment because it randomly assigns volunteers a sunscreen, while method A is an observational study.
Answer: Method B is an experiment because it randomly assigns volunteers a sunscreen, while method A is an observational study.
Step-by-step explanation:
Based on the information given, we can infer that method A is an observational study. An observational study simply refers to the study whereby the researchers just observe the impact of a rise factor without them trying to change the people or things exposed to it. This can be seen as the survey adults visited the beach on the busy weekend asking each adult the brand of sunscreen that they use and then assess their arms for sun exposure.
Method B is an experiment. An experiment refers to a test that's carried out in order to evaluate a particular hypothesis or theory. Method B is an experiment because it randomly assigns volunteers a sunscreen.

Find the volume of the cone in terms of pi. A cone with a radius of 5 feet and a height of 12 feet.
Answer:
V = [tex]\pi[/tex]r^2 x height
Step-by-step explanation:
Find the volume of the cone in terms of π. A cone with a radius of 5 feet and a height of 12 feet.
Answer:-Given:-Radius (r) of the cone = 5 feet.
Height (h) of the cone = 12 feet.
To Find:-The volume of the cone.
Solution:-We know,
Formula of Volume of Cone is [tex] \frac{1}{3} [/tex]πr²h
Volume of the cone = [tex] \frac{1}{3} [/tex]× π × (5)² × 12
Volume of the cone = [tex] \frac{1}{3} [/tex]× π × 5 × 5 × 12
Volume of the cone = [tex] \frac{\pi \: × \: 5 \: × \: 5 \: × \: 12}{3} [/tex]
Volume of the cone = [tex] \frac{300\pi}{3} [/tex]
Volume of the cone = 100π in³
Volume of the cone is 100π in³.
Hence, option (d) 100π in³ is correct. [Answer]A snow cone holder is a cone with a diameter of 3 inches and the height of 3 inches what is the volume of the snow cone holder
