Answer:
We write 4 times 4 because it includes 34,44,54,64in the data.
X=25 and u would add 5x to both sides 6x=25+5x then u would multiply both sides by 0.25 making it 1.5x=6.25+1.25x
Answer:
Cost of 1 hamburger = $1.3
Step-by-step explanation:
Assume;
Cost of 1 hamburger = a
Cost of 1 French fries = b
On first trip
3a + 4b = 7.10......eq1
On second trip
2a + b = 3.40....eq2
From eq2 x 4
8a + 4b = 13.6....eq3
From eq3 - eq1
5a = 6.5
a = 1.3
Cost of 1 hamburger = $1.3
Remember, you take 1/2 of b and square it to get c
c=100
(b/2)^2=c
(b/2)^2=100
sqrt oth sides
b/2=+/-10
times both sides by 2
b=+/-20
it is 20 or -20
answe ris B
yo is right
Answer:
65 degrees
Step-by-step explanation:
Since complementary angles are 2 angles that add up to 90 degrees, all you have to do is subtract 25 from 90.
When you do that you get 65.
Example: 90 - 25 = 65
