Answer
Yes, they are equivalent.
Step-by-step explanation:
10x2=20
13x2=26
Answer:
1) 12/18
2) 15/25
3) 32/40
4) 6/14
5) 8/15
6) 16/24
7. 12/27
Step-by-step explanation:
Answer:
1.=6 2.=7.6 3.= 2.2 6.= 3.50
Step-by-step explanation:
1. 78-27 =51 51 divided by 8.50=6
2.150-27=123 123 divided by 16=7.6
3. 14-65=51 51 divided by 23=2.2
6. 10 divided by 3= 3.5
No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
Answer:
(- 1, 4 ) and (2, 7 )
Step-by-step explanation:
Given the 2 equations
y = x² + 3 → (1)
y = x + 5 → (2)
Substitute y = x² + 3 into (2)
x² + 3 = x + 5 ← subtract x + 5 from both sides
x² - x - 2 = 0 ← in standard form
(x - 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 2 : y = 2 + 5 = 7 ⇒ (2, 7 )
x = - 1 : y = - 1 + 5 = 4 ⇒ (- 1, 4 )
