Answer:
1/5 or 0.2
Step-by-step explanation:
-5(p+3/5)=-4
Let's convert 3/5 to decimal form:
-5(p+0.6)=-4
Expand parentheses:
-5p-3=-4
Add -3 to both sides:
-5p=-1
Divide both sides by -5:
p=1/5 or 0.2
Hope this helps!
Answer:

y + 4 + 6
y − 4

2
Step-by-step explanation:
To set up the equation you would take x and add the nine pounds that Charlie weighs more than his brother and the set that equal to 99. Your equation would be X+9=99. If you wanted to take it a step further and solve the equation you would distract 9 from both sides which means that x=90
The parts of the sum are 55 and 80.
Step-by-step explanation:
Let,
'x' be the smaller part and
'y' be the greater part of the number.
The sum is x+y = 135. --------(1)
The greater part y = x+25. ---------(2)
Substitute (2) in (1),
⇒ x+(x+25) = 135
⇒ 2x+25 = 135
⇒ 2x = 110
⇒ x= 110/2
x = 55
The smaller part is 55.
Substitute x=55 in (2)
y = 55+25 = 80
The greater part is 80.
Answer:
The answer would be -439
Step-by-step explanation:
To find this, start by finding t(-7)
t(x) = 3x
t(-7) = 3(-7)
t(-7) = -21
Now that we have this answer, we input it into the s(x) equation.
s(x) = 2 - x^2
s(-21) = 2 - (-21)^2
s(-21) = 2 - 441
s(-21) = -439
