Create an equation to figure out how much salad was sold that day. S is for the number of salads. D is for the number of drinks.
$6.5s + $2d = $836.5
<span>s + d = 209
</span><span>s = 209 - d
Plug in the values.
</span>6.5 (209 - d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116
<span>s = 209 - 116
= 93
</span>

Answer:
x=2
HPT 3x+5y=6 (1) và 2x+y=4 (2)
Nhân phương trình (2) với 5 để hệ số y của 2 phương trình bằng nhau. Ta có:
(2)⇔ 10x+5y=20(3)
Trừ (3) cho (1), có: 7x+0y=14⇒x=2
(x-8)²= x²-16x+64
x²-16x+8=0
Therefore 56 must be added.
Good luck
To organize the expressions according to the number of terms, you should understand what a term is. A term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs. It is organized as follows:
2x2y + x2 - 3x + 4
3x + y + z
x + 2xyz
9x2yz
Answer:
once
Step-by-step explanation:
since the equation is liner, with x simply to the first power, it will only cross the x axis once. x^2 would cross the x axis twice, x^3 would cross it three times, and so on
