Answer:
Step-by-step explanation:
small=s, s=3.99
large=l, l=19.20
10s+8l=192.20
20s+l=99
we can see that in the second equation, 20s+l=99
l=99-20s
lets replace l in the first equation
10s+8(99-20s)=192.20
10s+792-160s=192.20
-150s=-792+192.20
150s=599.80
s=3.99
l=99-20(3.99)=99-79.80=19.20
Answer:
y = x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1, thus
y = x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = 5 + c ⇒ c = 3 - 5 = - 2
y = x - 2 ← equation of line
46 degrees Fahrenheit
You know it increased every five minutes so 30 divided by 5 is 6. That’s 6 times it has increased. 6 multiplied by 3 which is how many degree it’s increased each increment gives you 18. That’s the told it’s increased by 30 minutes. Then add the original temperature which was 28 to 18 which gives you 46.
Answer:
4 inch long and 3 inch wide
Step-by-step explanation:
so since the scale factor is 1 inch = 4 feet and the actual length is 16 feet by 12 feet all you got to do is divide both lengths by 4 and you get 4 and 3 and you convert the unit to inches so it would be 4 inches and 3 inches. now all you got to do is draw a 4 inch long by 3 inch wide rectangle and your good
