Hello!
To solve each expression, you need to substitute the given value for each given variable. If there is an <em>x</em> in the expression, then you substitute 5.07. If there's a <em>y</em>, then you substitute 1.5, and if there's a <em>z</em>, then you substitute 0.403.
7. 3.2x + y (substitute x = 5.07 and y = 1.5)
3.2(5.07) + (1.5)
16.224 + 1.5
17.724
8. yz + x (substitute y = 1.5, z = 0.403, and x = 5.07)
(1.5)(0.403) + (5.07)
0.6045 + 5.07
5.6745
9. z × 7.06 - y (substitute z = 0.403 and y = 1.5)
(0.403) × 7.06 - (1.5)
2.84519 - 1.5
1.34518
<u>Final answers</u>:
- Number 7: 17.724
- Number 8: 5.6745
- Number 9: 1.34518
Answer:
Step-by-step explanation:
you know the total angle is 180° from A to D
and you know that ∠BEC is 90°
also you are told that ∠CED is 18°
and that ∠AEB is 4x°
so just put that all together
180=90 + 18 +4x
now solve for X
180-90-18=4x
72=4x
18 = x
so now you know X
now solve ∠AEB
4(18) = 72°
∠AEB= 72°
