Answer:
x=9
Step-by-step explanation:
-5 square root x =-2+3
5x=4x^2 −12x+9
Simplify 25x-4{x}^{2}+12x-925x−4x 2 +12x−9 to 37x-4{x}^{2}-937x−4x 2-9
then...
(4x−1)(x−9)=0
x=1/4,9
-drop 1/4
x=9
Answer:
A solution of the system of equation given in the question is;
(2) x = 7 and y = 23
Step-by-step explanation:
The given system of equation are;
2·x + 3·y = 83...(1)
y = 2·x + 9...(2)
Substituting the value of y = 2·x + 9 from equation (2) into equation (1) gives;
2·x + 3·y = 2·x + 3 × (2·x + 9) = 83
∴ 2·x + 6·x + 27 = 83
8·x = 83 - 27 = 56
x = 56/8 = 7
x = 7
By substituting the value of x = 7 derived above into equation (1), we have;
y = 2·x + 9
Where;
x = 7
y = 2 × 7 + 9 = 14 + 9 = 23
y = 23.
Answer:
The slope of Zane is 18.50/2 = 9.25
Subtract both slopes to find the true statement.
10.5 - 9.25 = 1.25
The correct statement is:
Abrielle earns $1.25 more than Zane.
10. 4,200 cm
This is the correct answer!
Answer:
9.8 inches
Step-by-step explanation:
<h3>Formula for volume of the sphere is = 4/3πr³</h3><h3>Form and solve the equation for the radius</h3><h3>So: 4/3πr³= 498in³</h3><h3>πr³= 498in³*3/4 which = to 373.5in³</h3><h3>r³= 373.5in³/π</h3><h3>r=∛(373.5in³/π)</h3><h3>calculate r and times the result by 2 for diameter</h3><h3>it will be 9.834...</h3><h3>nearest tenth of an inch means the accuracy is 1 decimal place because nearest tenth= 1/10 or 0.1</h3><h3>So the final answer is 9.8in</h3>
