Hey there!
The answer to your question is 94.5
We can use this equation, and solve: (we need to use "2x" because the score counts for 2 grades!)
(89 + 79 + 93 + 2x) / 5 = 90
(261 + 2x) / 5 = 90
261 + 2x = 450
2x = 189
x = 94.5
To check if it's right, we can add up all the scores, and divide by 5, and see if it's equal to 90. (Make sure to use 94.5 twice because it counts for 2 test grades!)
(89 + 79 + 93 + 94.5 + 94.5) / 5
450 / 5
90 ✔️
Hope it helps! Have a great day and good luck!

Explain how solving -7y > 161 is different from solving 7y > -161.
Answer:
what the person above me said is correct :)
Step-by-step explanation:
Answer:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>
Step-by-step explanation:
If the volume of a cylinder is 900 cm squared with a height of 20 cm, what
is the diameter of the cylinder? Round to the hundredths.
Answer:
The diameter is 7.6 cm
Step-by-step explanation:
Mathematically, the volume of a cylinder can be calculated using the formula;
V = pi * r^2 * h
From the question;
V = 900
r = ?
h = 20
Substituting these values
900 = 3.142 * r^2 * 20
r^2 = (900)/(3.142 * 20)
r^2 = 14.32
r = √14.32
r = 3.78 cm
Mathematically, the diameter is 2 times the radius
We have this as;
2 * 3.78 = 7.6 cm
On a test, Sarah got 48 questions correct out of 50. What percent did she get on her test?
Answer:
96%
Step-by-step explanation:
48 / 50 = 0.96
0.96 x 100% = 96%
Sara got a 96% on her test
she got a 48/50. Percentage is 'something'/100. So you * both sides by 2 so 50 is 100 and 48 is 96

Answer:
- 13x² + 7x + 6
Step-by-step explanation:
- 4x² + 6 - (9x² - 7x) ← distribute by - 1
= - 4x² + 6 - 9x² + 7x ← collect like terms
= - 13x² + 7x + 6

Step-by-step explanation:
The given equations are :
y=-x+2 ....(1)
y = -4x +7 ....(2)
From equation (1) and (2)
-x+2 = -4x +7
Taking like terms together
-x+4x=7-2
3x = 5
x = 1.667
Put the value of x in equation (1)
y=-(1.667)+2
y = 0.333
The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.
