= 9
Let's solve your equation step-by-step.
8.88=4.44(x−7)
Step 1: Simplify both sides of the equation.
8.88=4.44(x−7)
8.88=(4.44)(x)+(4.44)(−7)(Distribute)
8.88=4.44x+−31.08
8.88=4.44x−31.08
Step 2: Flip the equation.
4.44x−31.08=8.88
Step 3: Add 31.08 to both sides.
4.44x−31.08+31.08=8.88+31.08
4.44x=39.96
Step 4: Divide both sides by 4.44.
#2
= y = -3
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by 5.
Answer:
(x-1)^2 + (y+4)^2 = 9
Step-by-step explanation:
We can write the equation for a circle as
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
Substituting in (1,-4) for the center and 3 for the radius
(x-1)^2 + (y- -4)^2 = 3^2
(x-1)^2 + (y+4)^2 = 9
3x+3y +2(2x-y) matches up with 7x+y
x-4x+6y+ (14x-5y) matches up with 11x+y
(5x-3y) -x+3x-5y matches up with 7x-8y
5(x+y) +6(x-y) matches up with 11x-y
The improper fraction equal to the mixed number 3 3/8 is C. 27/8
Answer:
<h3>1.47 * 10^8</h3><h3>
</h3>
Step-by-step explanation:
Given the value 141700000, we are to express in scientific notation
The standard form is expressed as A * 10^n
A is any integer between 1 and 10
n is also any integer
141700000.= 1.47 * 10^8
Note that the decimal point was shifted back 8 times, main reason the power is 8
