Answer:
is there answer choices? if not im just guessing so dont take my word for it but i would say 8.5 servings.
We have that
the expressions is <span>∑ i=1 to 5 (4i)
for i=1-----------> (4*1)=4
</span>for i=2-----------> (4*2)=8
for i=3-----------> (4*3)=12
for i=4-----------> (4*4)=16
for i=5-----------> (4*5)=20
∑ i=1 to 5 (4i)=[4+8+12+16+20]=60
the answer is 60
Basically just convert this into an equation:
Let’s use “x” as the result
“•” is the multiplication symbol
Double s: s•2
Subtract t from result: =x-2
So, s•2=x-2
Answer:
(4,1)
Step-by-step explanation:
2x+4y=12
y=x-3
2x+4*(x-3)=12
2x+4x-12=12
6x=24
x=4
y=4-3=1
(4,1)
