Step-by-step explanation:
isn't these simultaneous equations? you need to use either substitution or elimination method to solve. u can't just find like that
Answer:
13
Step-by-step explanation:
9 more than a number y is
y + 9
If the number y is 4, then you have
4 + 9 = 13
<span>X-2/y=2
</span><span>-2/y=2-x
</span><span>2/y=-2+x
</span><span>1/y=(-2+x)/2
</span>y=1/(<span>(-2+x)/2)
</span>y=2/<span>(-2+x)</span>
Answer:
v > -6
Step-by-step explanation:
2*v-(-12)>0
Pulling out like terms :
1.1 Pull out like factors :
2v + 12 = 2 • (v + 6)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by 2
Solve Basic Inequality :
2.2 Subtract 6 from both sides
v > -6
Inequality Plot :
2.3 Inequality plot for
2.000 X + 12.000 > 0
You would set up the proportion 25/X= 32/100.
25*100 is 2500, 32*x is 32x
2500 = 32x
/32 /32 dividing by 32 on both sides
78.125 = x
