Answer:
6 packages B
7 packages A
Step-by-step explanation:
let the number of packages A be a and the number of packages B be b
Total number of packages is 13;
Thus;
a + b = 13 •••••(i)
Total package a cost is 18(a) = 18a
Total package b cost is 22(b) = 22b
Total of both is 258
18a + 22b = 258 •••••••(ii)
From i, a = 13-b
Put this in equation ii
18(13-b) + 22b = 258
234-18b + 22b = 258
4b = 258-234
4b = 24
b = 24/4 = 6
since;
a + b = 13
a + 6 = 13
a = 13-6
a = 7

It's not a right triangle because [tex]16^{2} + 18^{2} > 24^{2}[/tex]
Step-by-step explanation:
[tex]16^{2} + 18^{2} > 24^{2}[/tex]
[tex]16^{2} = 256\\\\18^{2} = 324\\\\256 + 324 = 580\\\\580>24^{2} \\\\24^{2} = 576\\\\580>576[/tex]

4 3/8 ÷ 1 3/8 = answer asap and correct
Answer:
3 2/11
Step-by-step explanation:
4 3/8 = 4 + 3/8 = 32/8 + 3/8 = 35/8
1 3/8 = 1 + 3/8 = 8/8 + 3/8 = 11/8
then:
4 3/8 ÷ 1 3/8 = (35/8) / (11/8) = 35/11
35/11 = 33/11 + 2/11 = 3 2/11
Answer:
[tex]4 \frac{3}{8} \div 1 \frac{3}{8} = \frac{35}{8} \div \frac{11}{8} = \frac{35}{8} \times \frac{8}{11} = \boxed{\frac{35}{11} }[/tex]

help me asap please, very much appreciated :)
Answer:
155°
Step-by-step explanation:
x + 25° = 180° {Being linear pair }
x = 180° - 25°
Therefore x = 155°
Hope it will help :)
Answer:
155⁰
Step-by-step explanation:
Total angle on a straight line = 180⁰
: 25⁰ + x⁰ = 180⁰
x⁰ = 180⁰ - 25⁰
x⁰ = 155⁰
You plan to purchase items for $4000 and will finance the cost with a fixed installment. The seller tells you that you will have to pay $100 per month for 48 months. (a) how much money will you pay for interest (ie the finance charge) (b) what is the interest percent rate? (c) If this loan is for 48 months, what should T be (in years)? Would you plug that into your equation
Answer:
800 ; 20% ; 4 years
Step-by-step explanation:
Actual price of item = $4000
Total amount paid in installment = ($100 * 48) = $4800
Finance charge = total amount paid in installment - actual price
Finance charge = $4800 - $4000 = $800
B) Interest percent rate, r :
r% of 4000 = 800
0.01r * 4000 = 800
40r = 800
r = 800/40
r = 20
r = 20%
C.)
Time in years ; for 48 months
T = 48/12 ; T = 4 years

I noticed there is only one answer for this question and the answer was..incorrect. Therefore can someone answer this for me?
y=2x+9
y=4x-3
..............................
x=-9/2
x=-3/4
x = 6
y = 21
Step-by-step explanation:y = 2x + 9
y = 4x - 3
2x + 9 = 4x - 3
• Get the like-terms together:
9 + 3 = 4x - 2x
12 = 2x
• Divide 2x and 12 by 2 (to get x by itself):
12 ÷ 2 = 2x ÷ 2
6 = x OR x = 6
• To find the value of y, we have to substitute x into one of the equations (it doesn't matter which equation you plug x into, if the value of x is correct, both will equal the same number):
y = 2(6) + 9
y = 12 + 9
y = 21
y = 4(6) - 3
y = 24 - 3
y = 21

It is recommended that backpackers should carry no more than 20% of their body weight on long hikes and no more than 10% of their body weight on short hikes.
Part A
A hiker who weighs 160 pounds is planning a long hike. The weight of their backpack when packed with essential equipment is 15 pounds. Write an inequality to show how many pounds, p, the hiker can still add to their backpack and stay within the recommended weight.
Part B
A hiker who weighs 180 pounds is planning a day hike. The weight of their backpack when packed with essential equipment is 7.5 pounds. How much weight can the hiker still add to their backpack and stay within the recommended weight?

Write and equati9n of a l8ne that passes through (1,-2) and is perpendicular to -4x+7y=21
Given:
A line passes through (1,-2) and is perpendicular to [tex]-4x+7y=21[/tex].
To find:
The equation of that line.
Solution:
We have, equation of perpendicular line.
[tex]-4x+7y=21[/tex]
Slope of this line is
[tex]m_1=-\dfrac{\text{Coefficient of x}}{\text{Coefficient of y}}[/tex]
[tex]m_1=-\dfrac{-4}{7}[/tex]
[tex]m_1=\dfrac{4}{7}[/tex]
Product of slope of two perpendicular lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]\dfrac{4}{7}\times m_2=-1[/tex]
[tex]m_2=-\dfrac{7}{4}[/tex]
Now, slope of required line is [tex]-\dfrac{7}{4}[/tex] and it passes through (1,-2). So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-2)=-\dfrac{7}{4}(x-1)[/tex]
[tex]4(y+2)=-7(x-1)[/tex]
[tex]4y+8=-7x+7[/tex]
[tex]4y+7x=7-8[/tex]
[tex]7x+4y=-1[/tex]
Therefore, the equation of required line is [tex]7x+4y=-1[/tex].

Graph y=-2x+5y=−2x+5y, equals, minus, 2, x, plus, 5.
Answer:
Please check the graph of the function y=-2x+5 attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the function
[tex]y=-2x+5[/tex]
comparing with the slope-intercept form of the line equation
The slope m = -2
The y-intercept b = 5
The graph of y=-2x+5 is attached below.
Determining the y-intercept from the graph
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
Please check the graph of the function y=-2x+5 attached below.

Find the slope of the line that passes through the following points. (-5, -2) (5, 2)
2/5
5/2
10/4
2 1/2
Answer:
The slope is 2/5
Step-by-step explanation:
Calculating the Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (-5, -2) (5, 2). Let's compute the slope:
[tex]\displaystyle m=\frac{2-(-2)}{5-(-5)}[/tex]
[tex]\displaystyle m=\frac{4}{10}[/tex]
Simplifying:
[tex]\displaystyle m=\frac{2}{5}[/tex]
The slope is 2/5
