Answer:
x = -3; substitute it to the other equation.
2(-3) - 7y = 30
-6 - 7y = 30
-7y = 30 + 6
-7y = 36
y = -36/7
we will not round the number because the question is asking for an improper fraction at its simplest form.
Answer:
3(2 + 3)
Step-by-step explanation:
both answers equal 15
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
According to the number of cups, 564 people can be invited to the party.
Step-by-step explanation:
This is a simple question of cross multiplication
<u>DATA:</u>
<em>1. Total number of cups of yogurt is 423 cups</em>
<em>2. 1 serving = th of a cup</em>
<em>3. Each guest gets of a cup or 1 serving</em>
<em>4. Find out how many guests can be invited to the party,</em>
Cups : People
: 1
423 : p
<em>5. Cross multiply</em>
p = 423 x 1
3p = 423 x 4
p =
p = 564
Therefore, according to the number of cups, 564 people can be invited to the party.
