Hey there! :)
<em>First, let's substitute y with 0.8, and multiply by 8</em>
0.8 × 8 = 6.4
Here is the new equation:
4x + 6.4 = 40
<em>Now, subtract 6.4 from 40</em>
40 - 6.4 = 33.6
That means 4x = 33.6
<em>Divide both by 4</em>
4x ÷ 4 = x
33.6 ÷ 4 = 8.4
x = 8.4
Hope this helps :)
Answer:
48° ,132
Step-by-step explanation:
x+(x-84)=180
2x=264
x=132
132-84=48
Answer:
x=50
Step-by-step explanation:
3x-5=145(vertically opposite angle)
3x=145+5
3x=150
x=150/3
x=50
DON'T FORGET TO WRITE DEGREE
19.32=density D=m÷v so, v=m÷d
v=575÷19.32 v=about 29.8
