4x + 10 = -26
-10 -10
4x = -36
Then -36 divided by 4
X= -9 -9 is the answer.
Answer:
11
Step-by-step explanation:
The two equations appear to be ...
- 12x +4y = 152
- 32x +12y = 420
These can be solved for y using Cramer's rule:
y = (152(32) -420(12))/(4(32) -12(12)) = -176/-16 = 11
The cost of the vegetarian lunch is 11.

<em>Comment on Cramer's Rule</em>
For equations ...
ax +by =c
dx +ey = f
The solutions are ...
x = (bf -ey)/(bd -ea)
y = (cd -fa)/(bd -ea) . . . . note the denominators are the same expression
Once you memorize the pattern of products, this can be the simplest way to solve a pair of equations--especially if you only need one of the variable values.
16 blocks = 4 steps
x blocks = 50 steps
(16 blocks x 50 steps)/4 steps
= 200 blocks
The population of Virginia is 7,980,000 people.
- Let the population of Virginia be V.
- Let the population of Georgia be G.
<u>Given the following data:</u>
- Population of Georgia = 10.5 million
To find the population of Virginia:
Translating the word problem into an algebraic expression, we have;
24% percent less:
× 
× 
24% of G = 2,520,000
Now, we can find the population of Virginia:


<em>V = 7,980,000 people.</em>
Therefore, the population of Virginia is 7,980,000 people.

Answer:
Sample model as the picture attached, which shows 2/3 of 18 are circled.
Step-by-step explanation:
Here is the correct question: Your class has 18 students. Exactly 2/3
of them say that, out of all their subjects, they like science the most. Which model shows 2/3 of 18 circled?
Given: Total number of student is 18.
2/3 of the total students like science the most.
Now, calculating the number students like the science the most.
∴ Number of students who like the science most= 
12 students like the science most out of total students.
Sample model are shown in the picture attached, where out of 18 students only 12 are inside the circle to show they like science the most.
