8 baseball cards + 5 football cards= 13 cards
8 baseball cards per every 13 total cards.
78÷13=6
6×8= 48
48 Baseball Cards in total
if I'm correct, 3 would be 78 as well . I'm so sorry if I get this wrong . I struggled a bit with this part and math a lot , and I only worked on it for like 2 days and then I had to test for it
(-3,3] is an interval which means that -3 and 3 are not inclusive of the values of x -5/3.
We have given
-3x+4 > 9
Required values of x.
State the values of x within -3 and 3.
subtract 4 from both sides,
-3x+4-4>9-4
<h3>What is the meaning of like terms?</h3>
like terms are terms that have the same variables and powers. The coefficients do not need to match.
Collect Like Terms
-3x > 5
(-3x)(-1) < 5(-1)
3x < -5
Divide both sides by 3
3x/3 < -5/3
x < -5/3
(-3,3] is an interval which means that -3 and 3 are not inclusive of the values of x is -5/3.

Answer:
D
Step-by-step explanation:
Range is the least number (50) subtracted from the greatest number (90)
90-50 = 40 (range)
The most dots is at 70 and the chart is symmetrical.
Answer:
So the roots of the polynomial are -7 , 4 , 2
Step-by-step explanation:
Given the polynomial in the question
5x³ + 5x² - 170x + 280
One of the factor of this polynomial is (x + 7)
By using remainder theorem
5x²-30x+40
-----------------------------------
x+7 | 5x³ + 5x² - 170x + 280
5x³ + 35x²
----------------------------
-30x² -170x + 280
-30x² -210x
------------------
40x + 280
40x + 280
----------------
0
So the polynomial we have is
5x²- 30x + 40
divide by 5
x² - 6x + 8
(x-4)(x-2)
So the roots of the polynomial are -7 , 4 , 2
