Answer: 1. x= -12 2. x= 12
Step-by-step explanation:
1. 5(+3)=−45
5x+15−15=−45−15
5x= -60
5x/5 = -60/5
x = -60/5
x= -12
2. 1x/2−4=2
x/2 -4=22−4+4=2+4
/2=6
2⋅2=2⋅6
x=2⋅6
x= 12

Isosceles triangle has two sides of equal length. The value of x is 4.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
As we see the diagram, the triangle has two angles same, it means two sides are equal. The given triangle is a isosceles triangle. Isosceles triangle has two sides of equal length.
so 4x+23=10x-1
take all variables on one side
4x-10x=-1-23
-6x=-24
Multiply both sides by negative sign and divide by 6
x=4
Hence the value of x is 4.

What is the 125th digit beyond the decimal point in the decimal representation of $\frac47$?
Answers
4/7 = 0.571428571428571428.....etc
Groups of 6 digits repeat. 125 = 5 mod(6), and the 5'th digit of the 6 repeating digits is 2, so this is the 125'th digit beyond the decimal point.
The 125th digit beyond the decimal point in the decimal representation of 4/7 is 4.
What is the number system?Number systems are mathematical systems that are used to express numbers in various ways.
The decimal representation of 4/7 is a repeating decimal: 0.5714285714...
The remainder when 4 is divided by 7, then multiply that remainder by 10¹²⁴ (since we're looking for the 125th digit beyond the decimal point), and divide the result by 7. The 125th digit beyond the decimal point will be the digit to the right of the decimal point in the resulting quotient.
Let R be the remainder when 4 is divided by 7. We can see from the long division above that R = 4.
So the 125th digit beyond the decimal point is the same as the first digit beyond the decimal point in the quotient of (4 × 10¹²⁴) / 7.
⇒ (4 × 10¹²⁴) ÷ 7 = 5714285714...
Thus, the 125th digit beyond the decimal point in the decimal representation of 4/7 is 4.

A grocery store sells bananas for b dollars a pound and
grapes for g dollars a pound.
Priya buys 2.2 pounds of bananas and 3.6 pounds of
grapes for $9.35.
Andre buys 1.6 pounds of bananas and 1.2 pounds of
grapes for $3.68.
This situation is represented by the system of
equations:
equation 1: 2.2b +3.6g = 9.35
equation 2: 1.65 +1.2g = 3.68
Explain why it makes sense in this situation that the
solution of this system is also a solution to
3.86 + 4.8g = 13.03.
Answers
To Find : Relationship between equations for price of bananas & grapes.
Given : Price of banana B, grapes G = b, g dollars per pound respectively. And, Bananas & Grapes bought by Priya & Andres.
Expenditure equations : ( B x b ) + ( G x g ) = Expenditure
Priya Expenditure equation : 2.2b + 3.6g = 9.35Andre Expenditure equation : 1.65 + 1.2g = 3.68Solving these two equations is similar to solving: Priya' & Andre' Total Expenditure { ie 9.35 + 3.68 = 13.03 } equation
Total bananas (Priya & Andre) = 2.2 + 1.6 = 3.8
Total grapes (Priya & Andre) = 3.6 + 1.2 = 4.8
So, final equation : 3.8 b + 3.8 g = 13.03

Tanya is printing a report. There are 100 sheets of paper in the printer, and the number of sheets p left after t minutes of printing is given by the function p(t) = -8t+100.
How long would it take the printer to use all 100 sheets of paper? Explain.
Answers
Answer:
12.5 minutes.
Step-by-step explanation:
The number -8 indicates that the paper uses 8 pages per minute. You can solve the equation by simply dividing 100/8.
You can also find the answer by solving the equation for the value t. Subtract 100 from both sides, and you will get -8t = -100. Then, divide both sides by -8 and you will get 12.5.
A car that is a gas- and electric-powered hybrid has recently hit the market. The distance travelled on 1 litre of fuel is normally distributed with a mean of 20 km and a standard deviation of 6 km. Find the probability (to 3 decimal places) that the car travels between 15 and 28 km on 1 litre of fuel.
Answers
Answer:
0.70631
Step-by-step explanation:
Given that :
Mean (m) = 20 km
Standard deviation (s) = 6 km
Probability that car travels between 15 and 28 km
Using the relation to obtain the standardized score (Z) :
p(x < 15)
Z = (x - m) / s
Z = (15 - 20) / 6
= - 0.8333
p(Z < - 0.833) = 0.20242 ( Z probability calculator)
(x < 28)
Z = (x - m) / s
Z = (28 - 20) / 6
= 1.333
p(Z < 1.333) = 0.90873 ( Z probability calculator)
0.90873 - 0.20242 = 0.70631
