Answer:
176 grams of zinc.
Step-by-step explanation:
4/9 = x/396 where x = the number of grams of zinc.
Cross multiply:
9x = 4*396
x = 4*396/9
x = 176 grams.
Answer:
Im pretty sure its graph A
Step-by-step explanation:
Let's use x to represent the number of hours since we don't know that.
750+250x<u><</u><u />2500
Subtract 750 from both sides.
250x<u><</u><u />1750
Divide both sides by 250.
x<u><</u><u />7
The most hours that they can do is 7, or it can be less.
Answer:
x=20
Step-by-step explanation:
45= measure of angle 6 (vertical angles)
45+ 5x+35 = 180 (Supplementary angles)
x=20
1. 9/10 + 7/9 = 81/90 + 70/90 = 151/90 = 1 61/90
2. 1/2-3/11 = 11/22-6/22 = 5/22
3. 2/5-1/15 = 6/15-1/15 = 5/15 =1/3
