Jose wants to buy his friends pizza at lunch. He has $36 to spend. The pizza costs $2.25 per slice. Which equation could be used to find the number of slices, x, he can buy?
Answer:
36 = 2.25(x)
Number of slices = 16 slice
Step-by-step explanation:
Given:
Total amount spend = $36
Cost of each slice = $2.25 per slice
Number of slices = x
Find:
Equation
Computation:
Total amount spend = Cost of each slice × Number of slices
36 = 2.25(x)
x = 16
Number of slices = 16 slice

The ratio of lions to tigers in the zoo is 3:5 if there are 9 lions how many tigers are there?
Answer:
1.) $54
2.) $21 left
3.) 15 tigers
Step-by-step explanation:
1.) If the original price of an item was $60, and it was reduced by 10%, that means it is now being sold at 90% of its original value.
To find out the new price, simply take the original value and multiply it by 90% (as a decimal).
60*.90=54
So the new price is $54
2.) This is simple subtraction. If you spend $45 on some CDs and $12 on a t-shirt, you spent a total of $57. Subtract $57 from your total of $78.
78-57=21
You are left with $21
3.) Ratios are all about multiplication. If the ratio of lions to tigers is 3:5, that means that the number of lions is going to be any factor of 3, as long as it corresponds to the same factor of 5 for the tigers.
For example, if there are 9 lions, there must be 15 tigers.
3*3=9
5*3=15
There are 15 tigers

A fruit juice company includes 1.247 ounces of orange juice in a 6.85 ounce bottle of mixed fruit juice. How much of the bottle of mixed fruit juice is not orange juice
Answer:
5.603 ounces
Step-by-step explanation:
From the information given, you know the ounces of orange juice included in a bottle and the ounces of mixed fruit juice that the bottle has. So, to be able to determine how much of the bottle of mixed fruit juice is not orange juice, you have to subtract the ounces of orange juice in the bottle from the ounces of mixed fruit juice that it has:
6.85-1.247=5.603
According to this, the answer is that the bottle of mixed fruit juice has 5.603 ounces that are not of orange juice.

Solve the following expression. d=5 2d+4d-9-7
Answer:
14Step-by-step explanation:
[tex]2d+4d-9-7\\\\d =5[/tex]
Substitute ; d= 5 into the given equation
[tex]2(5)+4(5) -9-7\\\\Follow\:the\:PEMDAS\:order\:of\:operations\\\\10 +20 -9-7\\\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:\\\\10+20 =30\\\\=30-9-7\\\\30-9=21\\\\=21-7\\\\21-7\\=14[/tex]
The value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The expression:
= 2d + 4d - 9 - 7
Plug d = 5 in the above expression:
= 2(5) + 4(5)- 9 - 7
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 10 + 20 - 9 -7
= 30 - 16
= 14
Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

I really need help on this problem.
Answer:
a.) 20
b.) 4/3
c.) 3
Step-by-step explanation:
a.) Plug in 5 for x
5(5) - 5
25 - 5
20
b.) Plug in 1/3 for x
5(1/3) - 1/3
5/3 - 1/3
4/3
c.) Set equation equal to 12 to find x input
12 = 5x - x
12 = 4x
3 = x
x = 3
this is integrated math2, help plzzzz. i’m so lost idk what this is:/
I remember doing the last question.
If you recall, x = 29
Just plug 29 into x for each angle
A = 3(29) = 87
B = 2(29) + 1 = 59
C = 29 + 5 = 34
Answer:
The value of angle C is 34°
Step-by-step explanation:
2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}
or, 6x + 6° = 180°
or, 6x = 180° - 6°
or, x = 174°/6
or, x = 29°
now,
value of angle C = x+5°
= 29°+5°
= 34°

I need this TONIGHT!!! Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 5 1/2% per year. How much is the stock worth now? (Round each money calculation you make to the nearest cent.) The stock is worth $ now.
Answer:
[tex]A\approx\$880.68[/tex]
Step-by-step explanation:
So, we know that Jolene bought an initial $750.
We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.
So, we can use the compound interest formula, which is:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.
So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:
[tex]A=750(1+0.055)^t[/tex]
Add:
[tex]A=750(1.055)^t[/tex]
Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:
[tex]A=750(1.055)^3[/tex]
Evaluate. Use a calculator:
[tex]A\approx\$880.68[/tex]
And we're done!
Formula: A = P(1 + r/n)^t
We have these variables:
P = 750
r/n = 0.055
t = 3
Substitute and simplify:
A = 750(1 + 0.055)^3
A = 750(1.055)^3
A = 880.68
Best of Luck!

The length of a rectangle is twice its width. The perimeter of the rectangle is 134 feet.
Answer:
L = 2w 134 = 2L + 2w
l= length
w=width
l=2w
P=Perimeter= 134 ft
P= 2(l+w)
= 2(2w+w)
= 2(3w) = 6w=134
w=134/6=22 1/3 ft
l= 2w = 2 x 22 1/3 = 44 2/3 ft

The sum of the measures of a triangle is 180 degrees.a triangle has angle measures of 5x+2,6x and 134.find the measures of x
Answer:
4
Step-by-step explanation:
6x + 5x+2 + 134 = 180 All triangles have 3 angles = 180. Combine
11x + 136 = 180 Subtract 136
11x = 180 - 136
11x = 44 Divide by 11
x = 44/11
x = 4

The number of hot dogs Ryan can eat varies directly with the amount of time he spends eating. If Ryan can eat 14 hot dogs in 6 minutes, how many hot dogs can he eat in 15 minutes? HELPPPPPPPPPPP
Answer:
35
Step-by-step explanation:
Let h represent the number of hot dogs Ryan eats in 15 minutes. Since the rates are the same, we have ...
dogs/minutes = h/15 = 14/6
Multiplying by 15 gives us ...
h = (15·14)/6 = 35
Ryan can eat 35 hot dogs in 15 minutes.
