t= 1.6, or rounded 2
Answer:
t = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
10t - 19 = 7t - 14
Subtract 7t from both sides;
3t - 19 = -14
Add 19 to both sides;
3t = 5
Divide both sides by 3;
t = [tex]\frac{5}{3}[/tex]
Which of the following polynomial functions is graphed below?
Answers
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

Find the area of this parallelogram.
5 cm height
7 cm width
Answers
Answer:
35 cm^2
Step-by-step explanation:
To find the area you need to find the width and height which we have.
Now all you need to do is to use the formula Height x Width= area
so replace height with 5 cm and width with 7 cm
5 cm x 7 cm = area
5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)
Hope this helps!

On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly
Answers
Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
So, total number of questions is 40.

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answers
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

Answers
Answer:
$162.50
Step-by-step explanation:
+$100
25x2.50= $62.50
+$62.50
100+62.50=162.50
Answer:
Each student should pay $6.50
Step-by-step explanation:
The question is not very clear.
If Mr. Richard has to pay to enter:
Total cost = $100 + ($2.50×26) = $165
Cost per student = [tex]\frac{165}{25}[/tex] = $6.60
Each student should pay $6.60
If Mr. Richard doesn't have to pay to enter:
Total cost = $100 + ($2.50×25) = $162.5
Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50
Each student should pay $6.50
