what are the solutions to (x+7)2 =81
Answer:
x = 33.5Step-by-step explanation:
Simplifying
(x + 7) * 2 = 81
Reorder the terms:
(7 + x) * 2 = 81
Reorder the terms for easier multiplication:
2(7 + x) = 81
(7 * 2 + x * 2) = 81
(14 + 2x) = 81
Solving
14 + 2x = 81
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + 2x = 81 + -14
Combine like terms: 14 + -14 = 0
0 + 2x = 81 + -14
2x = 81 + -14
Combine like terms: 81 + -14 = 67
2x = 67
Divide each side by '2'.
x = 33.5
Simplifying
x = 33.5
Answer:
x=16,−2

Answer:
a=43
Step-by-step explanation:
triangle equals 180.
180-47-90=43
Answer:43
Explanation
PQ=QR
QPR=QRP=47 (angles opposite to equal sides are equal)
PQR= 180-(47+47) = 86

5x2 - 45=0
Quadratic formula
Answer:
x=3
Step-by-step explanation:
5x²-45=0 | +45
5x² = 45 | :5
x² = 9 | /9
x = 3
Answer:
x=3,x=-3
Step-by-step explanation:
Use the quadratic formula
where
a=5
b=0
c=-45
which means x=(0±30)/10
so you do (0+30)/10=3
and (0-30)/10=-3

Patty’s gymnastics class is 5/6
of an hour long. Patty practices five different skills and spends the same amount of time on each skill. How can you find how much time she spent on each skill?
Explain how to use an area model to solve the problem
EXPLAIN !
Answer:
5/6 of an hour is 50 minutes.
Step-by-step explanation:
There are 60 minutes in 1 hour
5/6 = 50/60
If it is the same amount of time for all the skills, it would be 50 minutes in each skill.
Hope this helps. <3

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To find out how much time Patty spent on each skill, we can divide the total duration of Patty's gymnastics class by the number of skills she practices.
Given that Patty's gymnastics class is 5/6 of an hour long, we can represent the duration of the class as 5/6 hours.
Let's denote the time Patty spent on each skill as "x" hours.
Total time = 5x
The total duration of Patty's gymnastics class is 5/6 hours.
On simplifying the equation , we get
5x = 5/6
Divide by 5 on both sides , we get
5x/5 = (5/6)/5
x = 1/6
Hence , Patty spent 1/6 hours on each skill, or in other words, 1/6 of an hour on each skill

3) GRIP is a rectangle with: PS = 6x - 4
GI = 10x +4
m <1 = 2y +7 and
m3 = 6y +3.
Find:
a.) PR =
b.) m < 2 =
c.) m
Help please!
Answer:PR = 64; m∠2 = 63°; m∠RSI = 54°
because GRIP is a rectangle
=>PR = GI = 2PS
<=> 10x + 4 = 2.(6x - 4)
<=> 10x + 4 = 12x - 8
<=> 2x = 12
<=> x = 6
because PR = GI => PR = 10x + 4 = 10.6 + 4 = 64
GRIP is a rectangle => PS = SI
=> ΔPSI is a isosceles triangle
=> m∠1 = m∠2
but m∠2 + m∠3 = 90°
=> m∠1 + m∠3 = 90°
<=> 2y + 7 + 6y + 3 = 90
<=> 8y + 10 = 90
<=> 8y = 80
<=> y = 10
with y = 10 => m∠2 = 2.10 + 7 = 27
we also have: RS = SI
=> ΔRSI is a isosceles triangle
=> m∠3 = m∠4 = 90° - 27° = 63°
=> m∠RSI = 180° - 63°.2 = 54°

Answer:
gradient = -4/3
Step-by-step explanation:
information not complete, but this is the equation of a straight line, and assume you want to know the gradient
3y = 8 - 4x
3y = -4x + 8
dividing both sides by 3
y = -4/3x + 8/3
comparing the equation to equation of a straight line;
y = mx + c
m = -4/3
Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan's height in centimeters? *(HINT: CHANGE HIS HEIGHT TO INCHES - HOW MANY INCHES ARE IN A FOOT? HOW MANY INCHES ARE IN 4 FEET? THEN ADD 2 INCHES) *
Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres

Tony worked hours on his science project. Sonia worked times as long on her science project as Tony did. For how many hours did Sonia work on her science project?
Complete question :
Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did. For how many hours did Sonia work on her science project?
Answer:
5 5/6 hours
Step-by-step explanation:
Given that :
Hours worked by Tony = 4 2/3
Hours worked by Sonia = 1 1/4 times as long as Tony
Hence, hours worked by Sonia = 1 1/4 * 4 2/3
5/4 * 14/3
= 70 / 12
= 5 10/12
= 5 5/6 hours
