· Lucy buys 3 apples and 6 mangos for a total of $9.15.
· Amir buys 8 apples and 4 mangos for 11.92.
What is the cost of a single apple?
Answer:
0.97
Step-by-step explanation:
Let x be the cost of apples
Let y be the cost of mangoes
3x + 6y= 9.15......equation 1
8x + 4y= 11.92........equation 2
Multiply equation 1 by 8 and equation 2 by 3
24x + 48y = 73.2
-
24x + 12y = 35.76
36y = 37.44
y = 37.44/36
y= 1.04
Substitute 1.04 for y in equation 1
3x + 6y = 9.15
3x +6(1.04)= 9.15
3x + 6.24= 9.15
3x = 9.15-6.24
3x = 2.91
x = 2.91/3
x = 0.97
Hence the price of a single apple is 0.97

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityAlgebra I
Terms/CoefficientsSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
5x + y = 9
10x - 7y = -8
Step 2: Rewrite Systems
Manipulating: Equation 5x + y = 9
Subtract 5x on both sides: y = 9 - 5xStep 3: Redefine Systems
y = 9 - 5x
10x - 7y = -8
Step 4: Solve for x
Substitution
Substitute in x: 10x - 7(9 - 5x) = -8Distribute -7: 10x - 63 + 35x = -8Combine like terms: 45x - 63 = -8Add 63 on both sides: 45x = 55Divide 45 on both sides: x = 11/9Step 5: Solve for y
Define equation: 5x + y = 9Substitute in x: 5(11/9) + y = 9Multiply: 55/9 + y = 9Isolate y: y = 26/9The table shows a function. Is the function linear or nonlinear?
Answer:
linear
Step-by-step explanation:
linear equations are ones that go throught the origin if i remember correctly
Pls help this last question
Answer:
4 more pens
Step-by-step explanation:
Well, what do we know?
We know Sheila has:
6 pens
10 pencils
How many MORE pens does she need to make the number of pens equal to the number of pencils?
6 + x (x is the number of pens needed to EQUAL to 10)
6 + x = 10
x = 4
Sanity check:
6 + 4 = 10
Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.
what is the value of x in the equation -2/3 x + 9 = 4/3 x - 3
Answer:
x=6
Step-by-step explanation:
This equation requires simplifying. We start with moving like terms to each other:
3 + 9 = 4/3x + 2/3x
After this, add the like terms together:
12 = 6/3x
6/3 will simplify into 2:
12=2x
Finally, divide both sides by 2:
6=x

if if 30 per increase in the salary of usman results in rs.4500 what was the actual salary of usman
Answer:
The actual salary of usman was Rs. 3461.53
Step-by-step explanation:
Given that:
Percent increase in salary = 30%
Total salary percent would be = (100+30)% = 130%
Salary after increment = Rs. 4500
Let,
x be the actual salary before increase.
According to given statement,
130% of x = 4500
[tex]\frac{130}{100}x=4500\\1.3x=4500[/tex]
Dividing both sides by 1.3
[tex]\frac{1.3x}{1.3}=\frac{4500}{1.3}\\x=Rs 3461.53[/tex]
Hence,
The actual salary of usman was Rs. 3461.53

In chemistry class, Bob recorded the volume of a liquid as 12.7 ml. The actual volume was 12.3 mL. Use
the formula to find percent error of Bob's measurement to the nearest tenth of a percent.
Experimental Value - Actual Valuel
Percent Error =
Actual Value
x 100
The percent error of Bob's measurement is
%.
Answer:
% error = 3.3%
Step-by-step explanation:
Percent Error Formula:
% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100
% error = ( (12.7 - 12.3) / 12.3 ) * 100
% error = (0.4/12.3) * 100
% error = (0.03252033) * 100
% error = 3.25203252
% error = 3.3%

Answer:
4. x = 17
2. x = 77; y = 103
Step-by-step explanation:
4. The acute angles of a right triangle are complementary.
2x + 3x + 5 = 90
5x = 85
x = 17
2.
Same side interior angles are supplementary.
x + 103 = 180
x = 77
y and 103-deg angle are vertical angles, so they are congruent.
y = 103

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answer:
A = 81 - 20.25π
P = 36 - 9π
Step-by-step explanation:
To find the perimeter and area of the highlighted shapes, we must find those of the square and full circle. Then subtract the circle's area from the square. Do the same for perimeter.
