Answer:
Let's call the number of boxes Maria started with:
There are 37 boxes
Step-by-step explanation:
Let's call the number of boxes Kayla started with:
Then we can write:
22
=
b
+
7
2
Where:
22
is the number of boxes Kayla has left.
(
b
+
7
)
is the number of boxes Kayla started with plus the

she bought
The division by
2
represents

2
of the total boxes Kayla had being destroyed by fire.
We can solve this by first multiplying each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:

Maria has two options for buying a new computer. She can pay $750 right now, or she can pay $24.99 each month for 3 years. How much more will Maria pay if she makes payments for 3 years?
Answer:
$149.64
Step-by-step explanation:
Recall that there are 12 months in a year. Thus, 3 years would be 36 months.
$24.99 times 36 months comes to $899.64. To determine how much more Maria will pay by making monthly payments is $899.64 less $750, or $149.64.
A circle is shown. Secant X Z and tangent W Z intersect at point Z outside of the circle. Secant X Z goes through the center of the circle and intersects the circle at point Y. The length of W Z is k + 4, the length of Z Y is k, and the length of X Y is 12.
What is the length of line segment XZ?
Given:
Consider the below figure attached with this ques.
To find:
The length of the line segment XZ.
Solution:
According to the tangent-secant theorem, the square of tangent is equal to the product of secant and external segment of secant.
Using tangent-secant theorem, we get
[tex]WZ^2=ZX\times ZY[/tex]
[tex](k+4)^2=(k+12)k[/tex]
[tex]k^2+8k+16=k^2+12k[/tex]
[tex]8k+16=12k[/tex]
Subtract both sides by 8k.
[tex]16=12k-8k[/tex]
[tex]16=4k[/tex]
Divide both sides by 4.
[tex]4=k[/tex]
Now,
[tex]XZ=12+k[/tex]
[tex]XZ=12+4[/tex]
[tex]XZ=16[/tex]
Therefore, the measure of XZ is 16 units.

Hi! i'm showing this to my sister and she wants to know, At a yard sale, Jennifer sold 2 tricycles for $22.50 each, 3 old video games for $2.75 each, a video for $5.00, and a dictionary for 75 cents. How much money did she make?
Jennifer made $59.
$22.50 times 2 is $45 and $2.75 times 3 is $8.25, the sum of these numbers is $53.25.
$5 plus $0.75 is $5.75, and the sum of $5.75 plus $53.25 is exactly 59 dollars.
If this is incorrect, please, don't refrain to tell me.
Which measurements is equivalent to 4,000 centimeters? (100 centimeters = 1 meter)
Answer:
400 meters = 4000 centimeters
Step-by-step explanation:
Sorry if this didn't help
The solution is , 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.
Here,
we know,
100 centimeters = 1 meter
Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.
So, to convert 40 meters to centimeters, we can multiply 40 by 100:
40 meters = 40 x 100
= 4,000 centimeters
Therefore, 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

Which equation represents a nonlinear function? y=−85x+19.4 y = − − 8 5 x + 19.4 y=−12x2−7 y = − − 1 2 x 2 − − 7 y=x4+x y = x 4 + x y=32−4
Answer:
The answer is below.
Step-by-step explanation:
The options are not clear. I would solve a similar question.
A linear function is a function in the form:
y = mx + b; where y and x are variables, m is the slope and b is the y intercept.
From the options:
a) x(y - 5) = 2
xy - 5x = 2. Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.
b) y - 2(x + 9) = 0
y - 2x - 18 = 0
y = 2x + 18. The equation is in the form of y = mx + b, hence it is a linear function.
c) 3y + 6(2 - x) = 5
3y + 12 - 6x = 5
3y = 6x - 7. The equation is in the form of y = mx + b, hence it is a linear function.
d) 2(y + x) = 0
2y + 2x = 0
2y = -2x. The equation is in the form of y = mx + b, hence it is a linear function.

y=-x+2
y=3x-1
Answer:
x = 3/4
y = 5/4
Step-by-step explanation:
Step:
Substitute−x+2 for y in y=3x−1:
y=3x−1
−x+2=3x−1
−x+2+−3x=3x−1+−3x(Add -3x to both sides)
−4x+2=−1
−4x+2+−2=−1+−2 (Add -2 to both sides)
-4x = -3
x=3/4
Step: Substitute x into the original equation
y=-3/4 + 2
y=5/4

There are 32 ounces of water in a glass. Someone drinks 55% of the water. How many ounces of water are left? Answer without units.
Answer:
14.4
Step-by-step explanation:
If someone drinks 55%, that means 45% is left over. You multiply 32 x 45 to find out what is left.
Answer:
14.4
Step-by-step explanation:
lets start with the 55% it means 55/100
so we need to calculate the the ounces that the person drank which is:
32*15/100=17.6ounces
now to get the ounces left we should subtract the ounces that was drunk from the 32 ounces which is:
32-17.6=14.4
