You plug -x+16 in for y in x+4y=37 to get x after you multiply x+4y=37 by -1.
-x-4(-x+16)=-37
-x+4x-64=-37
3x-64=-37
3x=27
x=9
Then you plug 9 into either equation to get y.
y=-x+16
y=-(9)+16
y=7
x=9 and y=7
The number becomes in the unit form is a 5 hundreds and 0 tens and the 5 ones.
According to the statement
We have given that the number and the we have to write in the unit form.
So, For this purpose, we know that the
The unit form is the way to show how many of each size unit are in a number.
From the given information:
The number is a 505/10×10
Now, we have to solve this And the number becomes is
505.
And the
5 hundreds and 0 tens the 5 ones.
The unit form becomes the 5 hundreds and the 5 ones.
So, The number becomes in the unit form is a 5 hundreds and 0 tens the 5 ones.

The answer is C. Factor the equation: 2x^2 + 10x + 12 which gives you............. 2(x + 2) (x + 3), and then cancel out (x + 3) because dividing (x + 3) by itself gives you one and the remaining term is 2(x +2) which is the same as 2x +4.
Answer:
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Step-by-step explanation:
Let r be a ratio useful in determining how much of each ingredient Henry needs:
4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.
4/8 of the total 120 kg must then be 60 kg made up of cement;
3/8 must then be 45 kg made up of sand; and
1/8 must then be 15 kg made up of gravel
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Answer:
Step-by-step explanation:
Remember to break these apart by using the powers to determine the number the base and power make.
2^5 = 32
3^2 = 9
5 = 5
32 * 9 * 5 = 1440
