Answer:
98= 4p + 38
4p = 38 - 98
4p = - 60
P = - 60/4
P = -15
Answer:
p=15
Step-by-step explanation:
98=4p+38
(98-38)=4p
60=4p
(60/4)=(4p/4)
15=p
which mathematical process could be used to find the length of the side of a square, given it's area
Answer:
[tex] \sqrt{x} [/tex]
Step-by-step explanation:
the square root of what ever the area is. Area is length times width, but if all sides are the same then you just have to find the square root.

Tickets for the karaoke talent show sponsored by the Speech Club were priced at $3 for adults and $2 for students. The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.
Answer:
50 adults and 250 students tickets were sold
Step-by-step explanation:
Given data
Let the number of adults be x and students be y
3x+2y=650------1
x+y= 300---------2
from 2
x= 300-y
put the value of x in 1
3(300-y)+2y= 650
900-3y+2y= 650
900-y= 650
900-650= y
y=250
put the value of y in 2
x+250= 300
x= 300-250
x= 50
Hence 50 adults and 250 students tickets were sold

Brian bought 215 pounds of strawberries. In the afternoon his brother ate 56 of the strawberries. How many pounds of strawberries did his brother eat?
Hi there!
Step By Step:
We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.
Let think about this... 215 pounds are 215 strawberries.
If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.
We can also think like this... 56/215
Final Result: 56 pound sof strawberries.

A rectangle has length of 80cm and a width 50cm. And a scale factor of 3.5 what is the area in square cm of the dilated rectangle
Answer:
49,000 square cm
Step-by-step explanation:
To get the area of the dilated rectangle, we need the dilated dimensions
We simply multiply the scale factor by the dimensions
we have this as;
3.5 * 50 = 175 cm
and
3.5 * 80 = 280 cm
The area of the dilated rectangle is thus;
280 * 175 = 49,000 cm^2

Write a negative story using all four operations ( add, subtract, multiply, divide ) of integers as a part of the plot.
Answer:
BODMAS rule
Step-by-step explanation:
There are four basic rules in mathematics, Addition, subtraction, Multiplication and Division. All these operations can be used together or separately depending on the problem. When all the operation are required in the problem then BODMAS rule is applied to simplify the problem. BODMAS rule determines that operation will be performed according to the rule : Division, Multiplication, Addition and Subtraction. First operation which will be performed is division and last will be subtraction. This rule is same for all types of problems.

Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If BC=10BC=10 and DC=5,DC=5, what is the length of \overline{AC}? AC ?
Answer: [tex]\overline{AC}=[/tex] 12.5
Step-by-step explanation: The triangle ABC and its altitude [tex]\overline{BD}[/tex] is represented in the figure below.
Altitude is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of [tex]\overline{BD}[/tex], now we have two similar triangles, which means that ratios of corresponding sides are equal:
[tex]\frac{\overline{BD}}{\overline{BC}} =\frac{\overline{AD}}{\overline{BD}}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}.\overline{AD}[/tex] (1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.
[tex]\overline{BC}^{2}=\overline{CD}^{2}+\overline{BD}^{2}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}^{2}-\overline{CD}^{2}[/tex] (2)
Substituting (2) into (1):
[tex]\overline{BC}^{2}-\overline{CD}^{2}=\overline{BC}.\overline{AD}[/tex]
We want to find f, so:
[tex]\overline{AD}=\frac{\overline{BC}^{2}-\overline{CD}^{2}}{\overline{BC}}[/tex]
[tex]f=\frac{10^{2}-5^{2}}{10}[/tex]
f = 7.5
The length of [tex]\overline{AC}[/tex] is
[tex]\overline{AC}=f+5[/tex]
[tex]\overline{AC}=7.5+5[/tex]
[tex]\overline{AC}=12.5[/tex]
The length of the hypotenuse of triangle ABC is 12.5 units.

A middle school student reads 48 books in 31/3 years. Find the students reading rate in books per year
Answer: 14 2/5 books per year
Step-by-step explanation:
From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:
= Total books read / Number of years
= 48 ÷ 3 1/3
= 48 ÷ 10/3
= 48 × 3/10
= 144/10
= 14 2/5 books per year

Answer:
x = 4
Step-by-step explanation:
the given figure is of an isoceles triangle.
The two angles opposite are congruent(i.e78 degrees) .
That is the sides opposite to them are also congruent.
I. e 4x + 23 = 10x - 1
I. e 4x - 10x = -1 -23
I. e -6x = -24
I. e -x. = -24/6
Dividing by 6 to 24 we get,
-x = -4
therefore by removing the minus sign from both the sides,
the answer comes x = 4
