What they said ^ I was just about to answer, but there’s popped up first lol
Answer:
He made 5 cakes
Step-by-step explanation:
49 divided by 7 = 7
56 divided by 7 = 8
70 divided by 7 = 10
63 divided by 7 = 9
So for one cake you would need 7 g sugar, 8 g butter, 10 g flour, and 9 ml milk. So, 50 divided by 10 = 5 cakes
Answer:
a
Step-by-step explanation:
Answer:
Below
Step-by-step explanation:
● x^2 + 11x + 121/4 = 125/4
Substract 125/4 from both sides:
● x^2 + 11x + 121/4-125/4= 125/4 -125/4
● x^2 + 11x - (-4/4) = 0
● x^2 +11x -(-1) = 0
● x^2 + 11 x + 1 = 0
This is a quadratic equation so we will use the determinanant (b^2-4ac)
● a = 1
● b = 11
● c = 1
● b^2-4ac = 11^2-4*1*1 = 117
So this equation has two solutions:
● x = (-b -/+ √(b^2-4ac) ) / 2a
● x = (-11 -/+ √(117) ) / 2
● x = (-11 -/+ 3√(13))/ 2
● x = -0.91 or x = -10.9
Round to the nearest unit
● x = -1 or x = -11
The solutions are { -1,-11}
Answer:
3ac + bc
Step-by-step explanation:
c(3a + b)
Distribute (multiply) the c to the numbers in the parentheses.
c * 3a = 3ac c * b = bc
3ac + bc
