Answer:
X can be any number but because there is a line under the greater than symbol x > -42
Step-by-step explanation:
-42/7=-6
The answer is b.
when x decreases, f(x) decreases.
when x increases, f(x) increases.
Answer:
14. x = 1
16. x = 4
18. x = 10
Step-by-step explanation:
14. We have ∠ HGF = ∠ HGP + ∠ PGF
Given, ∠ HGF = 177x + 1, ∠HGP = 1 + 99x and ∠ PGF = 78°
So, 177x + 1 = 1 + 99x + 78
⇒ 78x = 78
⇒ x = 1 (Answer)
16. We have ∠ BCD = ∠ BCK + ∠ KCD
Given that, ∠ BCK = 9x - 2, ∠ BCD = 174° and ∠ KCD = 34x + 4
So, 174 = 9x - 2 + 34x + 4 = 43 x + 2
⇒ 43x = 172
⇒ x = 4 (Answer)
18. We have ∠ IJK = ∠ IJR + ∠ RJK
Now, given that, ∠ RJK = 8x + 10, ∠ IJR = 5x +8 and ∠ IJK = 148°
So, 148 = 5x + 8 + 8x + 10 =13x + 18
⇒ 13x = 130
⇒ x = 10 (Answer)
Step-by-step explanation:
<u>Step 1: Find the drop boxes</u>
The first drop box, the leftmost, is 3 since we multiply it again by three to get nine. Therefore both the first and second drop boxes are 3.
Answer: Both 3
There is another way to do this problem which is cross multiply
Question: What is 35 percent of 40?
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$40=100\%$40=100%.
Step 4: Similarly, $x=35\%$x=35%.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$40=100%(1).
$x=35\%(2)$x=35%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{40}{x}=\frac{100\%}{35\%}$
40
x=
100%
35%
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{40}=\frac{35}{100}$
x
40=
35
100
$\Rightarrow x=14$⇒x=14
Therefore, $35\%$35% of $40$40 is $14$ B. 14%
