Answer:
D
Step-by-step explanation:
If you multiply one side by 4, you have to multiply both sides by 4. D is the only one who multiplies both sides by 4, so it is the correct answer.
2) Abby spent $152 on Math Team spirit gear. Sweatshirts cost $25 and t-shirts cost $11. If she
bought a total of 10 items, how many of each type of shirt did she buy?
Answer:Abby bought 3 sweat shirts and 7 t shirt
Step-by-step explanation:
Step 1
Let sweat shirt be represented as s
and t shirts be represented as t
such that the total umber of items bought which equals 10 can be written as
s+ t= 10---- equation 1
and total price of the gear with each item costing $25 on sweatshirt $11 on t-shirts be expressed as
25 s+ 11 t = 152---- equation 2
Step 2
s+ t= 10-----equation 1
25s+ 11t= 152----equation 2
By elimination method , multiply equation 1 by 10 and subtract equation 2 from it
25 s+ 25t= 250----- equation 3
-25s + 11t= 152-----equation 2
14t=98
t=98/14= 7
To find s, using equation 1
s+t=10
s= 10-7= 3
Abby bought 3 sweat shirts and 7 t shirt
10 is 60% of what number please help
Answer:
600
Step-by-step explanation:
set x as the number
x0.10 = 60
x = 60/0.10
x = 600
Answer:
For me i think its 16.67 well im not fully sure
Step-by-step explanation:
SO we have to figure out what gives us 10 and that will be represented as "x"
[tex]\frac{60}{100}[/tex] × x = 10
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 10 × [tex]\frac{100}{60}[/tex] so, x = 16.67

Please do number 16 for me.
Answer: m∠5 = 75°.
Step-by-step explanation:
We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.
We know that:
"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"
Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)
Then the measure of ∠1 is the same as the measure of ∠5
And we know that m∠1 = 75°
Then we must have that m∠5 = 75°.

What is the sum of the interior angles of the figure shown
Answer:
C
Step-by-step explanation:
The sum of the interior angles of a square = 360° ( 4 right angles )
The sum of the interior angles of a triangle = 180°
Then sum of interior angles of the figure is
sum = 180° + 180° + 360° = 720° → C

What is the y-coordinate of the solution to the system of equations? 5x-y=25 4x+3y=1
Answer:
The y-coordinate of the solution is thus -5.
Step-by-step explanation:
Rewrite 5x-y=25 4x+3y=1
in a column:
5x-y=25
4x+3y=1
If we want to find the y-coordinate of the solution, we need to eliminate x. Solving the second equation for 4x yieds 4x = 1 - 3y, or
x = (1 - 3y)/4.
If this is inserted into 5x - y = 12, we get:
5(1 - 3y)/4 - y = 25, or (multiplying all terms by 4 to eliminate fractions):
5 - 15y - 4y = 100, or
-19y = 95, which yields y = -5
The y-coordinate of the solution is thus -5.
Solve the equation for all values of x by completing the square x^2-35=2x

Answer:
[tex]h=\frac{15.625}{pi}[/tex]
h ~ 4.974
Step-by-step explanation:
The formula for the volume of a cylinder is;
[tex](pi)(r^{2})(h)=V[/tex]
Where [tex](pi)[/tex] represents the value, [tex]3.1415...[/tex]
[tex](r)[/tex] represents the radius of the given cylinder. In other words, if one were to take a base (the flat side in the case of the cylinder) of the figure. The distance from the center to a point on the outside of the circle is the radius.
[tex](h)[/tex] represents the height of the object. In other words the distance between the two bases of the cylinder.
[tex]V[/tex] represents the volume, in other words, the space that the object takes up.
In this problem, one is given the diameter of the cylinder and the volume. One is asked to find the area.
The diameter of a circle is the distance between two opposite sides of the circle. The diameter will always pass through the center of the circle. To find the radius when given the diameter, one will divide by 2.
To solve this problem, one will substitute in the given information and solve for the height using inverse operations.
[tex](pi)(r^{2})(h)=V\\\\(pi)((\frac{8}{2})^{2})(h)=250\\\\(pi)(16)(h)=250\\\\(pi)(h)=15.625\\\\(h) = \frac{15.625}{pi}\\\\h- approx. 4.974[/tex]

The longest side of a triangle is 5 less than 3 times the shortest side and the remaining side is 4 cm. Find the lengths of the triangle if the perimeter is 19 cm
Answer:
4, 5, 10
Step-by-step explanation:
x=shortest side
one side =4
3x-5=long side
(3x-5)+x+4=19
4x-5+4=19
4x=20
x=5
long side = 3(5)-5=10
Beth has 250 comic books in her collection. She begins to sell 20 of them each week. Martin has 80 comic books in his collection. He begins buying 15 new comic books each week. Select from the choices below, dragging and dropping to build an inequality that could be used to determine when Martin's comic book collection exceeds Beth's.
Answer:
250 - 20 < 80 + 15x
Step-by-step explanation:
Given that
Beth has 250 books and 20 books sold each week
While on the other hand, Martin has 80 books and sell 15 books each week
Let us assume each week be x
Now the equations are
Beth 250 - 20x
Martin 80 + 15 x
Now the inequality would be
250 - 20 < 80 + 15x
Write the equation of the line, in slope-intercept form, with the
following information:
slope: -1
y-intercept: (0, -1)
Answer:
y = -x -1
Step-by-step explanation:
x1= 0, y1= -1
[tex]slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1} [/tex]
-1 = x/(y+1)
-1 (y+1) = x
y+1 = -x
y= -x -1
-3x = -x + 4
Plz help
Answer: x=-2
Step-by-step explanation:
Given
-3x=-x+4
Add x on both sides
-3x+x=-x+4+x
-2x=4
Divide -2 on both sides
-2x/-2=4/-2
x=-2
Hope this helps!! :)
Please let me know if you have any questions
Answer:
x = -2
Step-by-step explanation:
-3x = -x + 4
Add x to the left hand side to bring all like terms together.
-3x + x = 4
Combine like terms.
-2x = 4
Divide both sides by -2.
x = -2

The amount of money in a bank account increased by 17.5 % 17.5% over one year. If the amount of money at the beginning of the year is represented by A A, which expression below represents the amount of money in the bank account after the increase?
Answer: 1.175A
Step-by-step explanation:
From the information given in the question, we are told that the amount of money that is in a bank account increased by 17.5% while the money at the beginning of the year is represented by A.
The expression that represents the amount of money in the bank account after the increase will be:
= A + (17.5% × A)
= A + (17.5/100 × A)
= A + (0.175 × A)
= A + 0.175A
= 1.175A
