2x + 3y = 12
I am going to put this in y = mx + b form, where m is ur slope and b is ur y intercept.
2x + 3y = 12
3y = -2x + 12
y = -2/3x + 4......slope is -2/3 and y int is (0,4)
x int can be found by subbing in 0 for y and solving for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 6.....so x int is (6,0)
start at y int (0,4).....and since the slope is -2/3, come down 2 spaces, and to the right 3 spaces, then down 2 spaces, to the right 3 spaces....keep doing that and u should cross the x axis at (6,0)
Answer: 2.5%
3967.50 - 3450 = 517. 50
i = prt/100
i = 517.50, p = 3450, t = 6
517.50 = 3450 x r x 6/ 100
517.50 = 20700r/100
517.50 = 20700r
517.50/20700 = r
r = 0.025 = 2.5%
Divide the width by 2, as that is your scale.
26 / 2 = 13
The house would be 13 inches long.
To figure this out first make the 4 4/9 into a improper fraction making it 40/9 and then multiply 2/7 x 40/9 then make is a mixed fraction :) hope this helped.
Answer:
If the ratio is 7:5 and there are 42 girls, then you are multiplying by 6. 5 x 6 = 30. 30 boys participated.
Step-by-step explanation:
There are 30 boys in the competition.
Step-by-step explanation:
Given : The ratio of girls to boys who participated in the quiz bowl was 7:5. There were 42 girls in the competition.
To find : How many boys participated?
Solution : Let x be the number of boys in the competition.
There are 42 girls in the competition.
The ratio form by girls to boys is 42 : x
The ratio of girls to boys who participated in the quiz bowl was 7 : 5.
Solving the two ratios,
Therefore, There are 30 boys in the competition.
