Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936
4/18
With a six-sided die and 3 marbles there are 18 different outcomes.
(6 numbers • 3 marbles = 18 outcomes)
1/2 of the die is even (2,4,6) so that’s already a 3/6 chance of getting an even number. But since there is only one red marble there is a 1/3 chance of picking it. 3+1=4. 4/18
Answer:
He is 2 years old.
Step-by-step explanation:
She is 22, in 8 years she will be 30. 30 is 3×10. At that time, her brother will be 10; that is 8 years from now. So now, the little brother is 10-8 = 2 years old.
If you must show algebra work:
x = brother's age now.
x+8=brother's age in 8 years.
YingYu's age in 8 years = 3 × brother's age in 8 years
22+8 = 3(x+8)
30 = 3x +24
6 = 3x
2 = x
Answer:
x=-9.5
Step-by-step explanation:
y=-2x+3
y=22
Substitute the value of y into the given equation
22=-2x+3
Substrate 3 from both sides
19=-2x
Divide both sides by-2
x=-9.5
