<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1
</span>
for the above question, we can first convert the fractions to decimals to make it easier to work with
<span>1/10 of sand - 0.1 ton </span>
4/5 minute - 0.8 minute
<span>Q1 - </span>
<span>ratio </span>
0.1:0.8
since the ratio is in decimals we can convert it to whole numbers by multiplying by 10
1:8
Q2. amount of sand added in 0.8 minutes - 0.1 ton
<span> amount of sand added in 1 minute - 0.1/0.8 = 0.125 tons</span>

Answer:
J
Step-by-step explanation:
<h2>multiply 185 by 12=2220</h2><h3>you now know you need to find blank=2220</h3><h3 />
- F = 12(100)+12(13)
- G = 12(1)+12(8)+12(5)
- H= 12(18)+12(5)
- J= 12(100)+12(80)+12(5)
12*10=120
12*100=1200
12*12=144
12*13=156
12*18=216
12*5=60
12*8=96
f=1200+156=1356
g=12+96+60=168
h=216+60=276
j=1200+960+60=2220
