30 minutes. the easiest way is to use the opposite of the fraction. divide 25 / 5= 5. now multiply by 6. 5*6= 30.
Answer:
28 and 29
Step-by-step explanation:
the equation is x÷7≤4
26÷7= 3.7 ≠ x÷7≤4
27÷7= 3.8 ≠ x÷7≤4
28÷7=4
29÷7= 4.14=x÷7≤4
Its either A or C they both have the same spot when it is graphed.
X --- <span>first number
y --- </span><span>second number
x + y = 2x - 15
x - y = 2y - 5
x - 2x + y = -15
x - y - 2y = - 5
-x + y = -15
x - 3y = - 5
-----------------
-2y = -20 /:(-2)
y = 10
</span>x - 3y = - 5 ⇒ x = - 5 + 3y = - 5 + 3 · 10 = - 5 + 30 = 25
Ans.:
x = 25
y = 10
Answer:
a multiple of both is 5 ...
