The first you can multiply first equation by 2, you will get 16x - 12y = - 40, then add first equation to second
16x - 12y - 16x + 7y = - 40 + 30
-5y = - 10
Y= 2;
Then put y to first equation, because it easier.
8x - 2*6=-20
8x = - 8
X= - 1
Answer is x = - 1, y = 2.
these are some answers that can help you 15/40 or 6/9, 8/36, 12/90
Answer:
d ≤ 4
Step-by-step explanation:
4d + 7 ≤ 23
Subtract 7 from both sides:-
4d ≤ 16
d ≤ 4
Answer:
The second option
Step-by-step explanation:
The second option is correct because the base of the triangle, which is 3 cm, plus the base of the rectangle, which is 5 cm, is equal to the base of the trapezoid, which is 8 cm.
Hope this helps! :)
Answer:
The answer is 8.
Step-by-step explanation:
I used the calculator...
I just typed these equations on the calculator because its hard to do it in your head.
log 5root5 125 = 2 x=2
log 2root2 64 = 4 y= 4
The question wants the product of x and y which translates to x times y. x*y
SO.... 2*4 = 8
