Answer:
x² + 6
Step-by-step explanation:
Given
(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1
= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms
= x² + 6
Answer:
1/8th cup of marshmallows in each mug
Step-by-step explanation:
In order to split up the 1/2 cup of marhsmallows into 4 cups, you have to divide.
To divide, 1/2 by 4, you have to multiply 1/2 by the reciprocal of 4, which is 1/4.
1/2 x 1/4 = 1/8
Answer:
None of the above, it should be $4760
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year,
then, solving our equation
I = 3500 × 0.12 × 3 = 1260
I = $ 1,260.00
The simple interest accumulated
on a principal of $ 3,500.00
at a rate of 12% per year
for 3 years is $ 1,260.00
Answer:
x=5
y=1
Step-by-step explanation:
The substitution method is considered easier because of its simplification.
2x-3y=7 (1)
x+2y=7 (2)
considering equation (2),
x = 7 - 2y (3)
using the value of "x" in (1)
2 (7-2y) - 3y=7
14 - 4y- 3y = 7
14 - 7y = 7
7y = 14 - 7
7y = 7
y = 1 (4)
substituting this value of "y" in (3)
x = 7- 2(1)
x = 5
