Answer:
5 footballs were sold for every 2 basketballs sold.
Step-by-step explanation:
2.5 times as many football as basketball was sold last year
This can be represented as
1 basket ball sold = 2.5 footballs sold
for every 2 basketball sold, number of football sold = 2.5 x 2 = 5 footballs

if g(x) = 3 - 2x find g(-1)
Answer:
5
Step-by-step explanation:
g(x) = 3 - 2x
Let x= -1
g(-1) = 3 - 2*-1
= 3 - -2
= 3+2
= 5
Answer:
5
Step-by-step explanation:
g(-1)=3-(2(-1))
g(-1)=3+2
g(-1)=5
The difference of the squares of two positive consecutive even integers is 12. Find the integers. Use the fact that, if x represents an even integer, then x + 2 represents the next consecutive even integer
Answer:
2 and 4.
Step-by-step explanation:
(x+2)^2 - x^2 = 12
x^2 + 4x + 4 - x^2 = 12
4x + 4 = 12
4x = 8
x = 2.
Hence the integers are 2 and 4.
Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determine two values of x x that support your conclusion. x − 5 = x−5= 5 − x 5−x
Answer:
It has 1 solution
[tex]x=5[/tex]
Step-by-step explanation:
Given
[tex]x - 5 = 5 - x[/tex]
Required
Determine the number of solution
[tex]x - 5 = 5 - x[/tex]
Collect Like Terms
[tex]x + x = 5 + 5[/tex]
[tex]2x = 10[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} = \frac{10}{2}[/tex]
[tex]x = \frac{10}{2}[/tex]
[tex]x = 5[/tex]
Since the value of x is 5, then the equation has 1 solution
[tex]x = 5[/tex] is its only value

Which model represents a fraction less than Three-fifths? A circle divided into 5 equal parts. 4 parts are shaded. A circle divided into 5 equal parts. 2 parts are shaded. A circle divided into 5 equal parts. 6 parts are shaded. A circle divided into 10 equal parts. 8 parts are shaded.
Answer:
The correct answer is:
A circle divided into 5 equal parts. 2 parts are shaded.
Step-by-step explanation:
To determine the fraction less than three-fifths, let us convert the word problems into figures and compare the values:
[tex]Three-fifths = \frac{3}{5} = 0.6[/tex]
a) A circle divided into 5 equal parts. 4 parts are shaded (four-fifths)
[tex]Four-fifths = \frac{4}{5} = 0.8\ (more\ than\ three-fifths)[/tex]
b) A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)
[tex]Two-fifths = \frac{2}{5} = 0.4\ (less\ than\ three-fifhs)[/tex]
c) A circle divided into 5 equal parts. 6 parts are shaded = [tex]\frac{6}{5} = 1.2[/tex] (more than three-fifths)
d) A circle divided into 10 equal parts. 8 parts are shaded [tex]= \frac{8}{10} = 0.8\ (more\ than\ three-fifths)[/tex]
Therefore, the fraction less than three-fifths = A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)
A circle divided into 5 equal parts. 2 parts so the answer is B

1. Each of the six cards shows a shape.
N
3
X
5
4
z
a. Which pair of cards shows a shape and its image after a rotation?
b. Which pair of cards shows a shape and its image after a reflection?
Answer:
a). Cards (1) and (4)
b). Cards (3) and (5)
Step-by-step explanation:
(a). From the cards attached,
If card (1) is rotated by an angle of 180° counterclockwise, we get the image given in card (4).
Therefore, card (4) will be the image of card (1) after a rotation.
(b). If we reflect card (3) across a horizontal line (or x- axis) image card (4) is obtained.
Therefore, card (3) and card (5) is the pair of cards.

A function f satisfies f(2)= 3 and f(3) = 5. A
function g satisfies g(3) = 2 and g(5) = 6. What is
the value of f(g(3)) ?
A.) 2
B.) 3
C.) 5
D.) 6
Answer:
B. 3
Step-by-step explanation:
Start with the inside brackets where we have g(3). As seen, g(3) is given to be =2 so g(3) inside the bracket is now replaced with 2, giving us f(2). F(2) is given as 3, therefore the answer is B. 3

Solve for x. Round if needed. Image is below.
Answer:
x = 16
Step-by-step explanation:
3x + 1 = 49 ( vertical angles )
Subtract 1 from both sides )
3x = 48 ( divide both sides by 3 )
x = 16
The parking lot at a grocery store has 90 cars in it. 90% of the cars are blue. How many cars are blue?
a 10 cars
b 81 cars
c 810 cars
d 100 cars
Answer:
81 blue cars
Step-by-step explanation:
Total Cars = 90
How much % are blue = 90
=> 90 x 90/100 = How many cars are blue
=> 8100/100 = the number of cars that were blue
=> 81 = cars that were blue.
There 81 blue cars in the parking lot.
please someone help me to prove this..

What is m RMS in the figure below?
RA
P
M
128°
T
A 26
B 38
C 52
D 128
Answer:
Option (B)
Step-by-step explanation:
There are two lines PS and QT intersecting each other at a point M.
It's given that m∠PMT = 128° and m∠QMR = 90°
Since ∠PMT and ∠QMS are the vertical angles so these angles will be equal in measure.
∠PMT = ∠QMS
128° = m∠QMR + m∠RMS
128° = 90° + m∠RMS
m∠RMS = 128° - 90°
m∠RMS = 38°
Therefore, Option (B) will be the answer.
