To solve for the system of equations, I will write the equation down as I rewrite the written form.
a number, n, (n) is added to 15 less than 3 times itself (+3n -15). The result is (=) 101. (101)
Now let's write only what's in the parenthesis.
n + 3n -15 = 101.
The correctly written form in your answers is:
3n - 15 + n = 101, your first answer.
Answer:
-22
Step-by-step explanation:
6j-5k=11
5j-6k=22
-----------------
5(6j-5k)=5(11)
-6(5j-6k)=-6(22)
-----------------------
30j-25k=55
-30j+36k=-132
-----------------------
11k=-77
k=-77/11
k=-7
6j-5(-7)=11
6j+35=11
6j=11-35
6j=-24
j=-24/6
j=-4
------------------
2j+2k=2(-4)+2(-7)=-8-14=-22
Answer:
18.95(0.3+0.1)
Step-by-step explanation:
Add the parenthesis and then multiply it to the cost to get the answer
Draw a picture of the yard, rectangle. On the two long sides, write 28 yards and on the two shorter ones, just write a question mark.
To figure out perimeter, you need to add up each side.
P = Perimeter
L = Length
W = Width
P = L(2) + W(2)
If the length is 28, double it. = 56
Now subtract that from the perimeter - 88-56=32
32 is what you have left, so now split that, and replace the question marks.
All-in-all each width is 16 yards, while each length is 28, making the whole rectangle have a perimeter of 88 yards.
