Step-by-step explanation:
Step one:
given data
let the shirts be x
and the pants be y
Required
the number of shirts and pants
the systems of the equation for the situation is
2x+6y=11-------------1
5x+8y=18.75-------2
2x+6y=11-------------1X 5
5x+8y=18.75-------2 X2
10x+30y=55-------------1
-10x+16y=37.5-------2
0x+14y=-17.5
divide both sides by 14
y=17.5/14
y=1.25
pants= $1.25
put y=2.32 in eqn 1 2x+6y=11
2x+6(1.25)=11
2x+7.5=11
2x=11-7.5
2x=3.5
x=3.5/2
x=$1.75
Shirts = $1.75

100 ÷2 [1500 ÷5 {6 + (21 + 7 - 24)}] please solve this step by step
Step-by-step explanation:
100 / 2 (1500/5 (6 + (21 + 7 - 24)))
= 100 / 2 (1500/5 (6 + (28 - 24)))
= 100 / 2 (1500/5 (6 + (4)))
= 100 / 2 (1500/5 (10))
= 100 / 2 (300 (10))
= 100 / 2 (3000)
= 50 (3000)

PLEASE FAST!!: (math related, view picture) Liner equation: y= 3x-4
Somebody please draw/show how they did the map so i can do it. i need help!!
Answer:
Step-by-step explanation:
y = 3x - 4
x = 0, y = 3*0 - 4
y = -4
(0 , -4)
x = 1 , y = 3*1 - 4
y = 3 - 4
y = -1
(1 , -1)
x = 2 , y = 3*2 - 4
y = 6 - 4
y = 2
(2 , 2)
Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points
how many liters are in 21 cups? if 1L=4.2cups
i don't understand how to do it
Answer:
5 L
Step-by-step explanation:
As given in question,
1 L can fill 4.2 cups.
So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.
Therefore,
21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21
= 5 L
So, there is 5 L of fluid in 21 cups.

When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent. G-CO.10 2. In triangle ABC, ∠ = ∠ = . Which of these can be proved using the triangle s
Answer:
The correct option is;
D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
Step-by-step explanation:
In the proof to show that the sum of the angles in a triangle = 180°, we have;
For a triangle located between two parallel lines, such that the base of the triangle coincides with one of the parallel lines, we have;
The angle formed by one of the base angles and the adjacent side of the extension = 180° by the sum of angles on a straight line
From the attached diagram of a triangle between two parallel lines, we have;
∠e + ∠b = 180° by the sum of angles on a straight line postulate
∠e = ∠a + ∠d by alternate interior angles postulate
∠c = ∠d by alternate interior angles postulate
∴ ∠e = ∠a + ∠c by substitution property
∴ ∠e + ∠b = ∠a + ∠c + ∠b = 180° by substitution property
Therefore, the sum of the interior angles of a triangle, ∠a + ∠c + ∠b = 180°.

A baseball is hit from home plate at an initial velocity of 32 feet per second from a height of 5.5 feet. How long will it take for the ball to descend to an outfielder's glove 6 feet off the ground?
Answer:
t=0.19
Step-by-step explanation:
Velocity is distance per tine
V=s/t
32=5.5/t
t= 0.72
To know How long will it take for the ball to descend to an outfielder's glove 6 feet off the ground?
V=s/t
32=6/t
t=0.19

Answer:
x column- 1.25, 7.5, 45.
y column- 5, 30, 180.
Step-by-step explanation:
Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.
write an exponential function in the form y=ab^(x) that goes through points (0,4) and (6, 2916)
Answer:
y=4(3)^x
Step-by-step explanation:
The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ
What is the exponential function?An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.
Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)
The exponential form of an equation is given by =
y = abˣ
Where, a is the y-intercept,
a = 4 here,
y = 4bˣ
Now substitute 6 for x and 2916 for y,
2916 = 4(b)⁶
b⁶ = 729
b = 3
Therefore,
y = 4(3)ˣ
Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

The basketball team spends 20 minutes running laps and at least 15 minutes discussing plays. Practice lasts one hour and 45 minutes. Write an inequality to represent the amount of time to work on other drills. Just type in the final answer. Let: x=other drills
Answer:
x ≤ 75
Step-by-step explanation:
The computation of the inequality function is as follows:
Let us assume the remaining time left for other drills be x
Given that the team spends 20 minutes for running laps
And minimum of 15 minutes for discussing plays
Also practicing for last one hour and 45 minutes
Now as we know that
1 hour = 60 minutes
So total minutes would be
= 60 + 45
= 105 minutes
Total minutes spend by the team is
= 20 + 15
= 35 minutes
So now the remaining time left is
x ≤ 105 - 35
x ≤ 75
