Answer:
Step-by-step explanation:
'n' = a number
1/3n - 8 = -13
add 8 to each side to get:
1/3n = -5
n = -5(3)
n = -15
Check:
1/3(-15) - 8 = -13
-5 - 8 = -13
-13 = -13

Answer:
5x-4y = -32
Step-by-step explanation:
We can first get an equation in point slope form since we have a point and a slope
y-y1 = m ( x-x1) where m is the slope and (x1,y1) is a point on the line
y- -2 = 5/4(x- - 8)
y+2 = 5/4 (x+8)
Multiply each side by 4 to get rid of fractions
4(y+2) = 5/4 *4 (x+8)
4(y+2) = 5(x+8)
Distribute
4y+8=5x+40
Subtracy 4y from each side
8 = 5x-4y+40
Subtract 40 from each side
8-40 = 5x-4y
-32 = 5x-4y
5x-4y = -32
Silvia filled a watering can with 3.48 liters of water. She used 40 milliliters to water her cactus plant and 150 milliliters to water her rose plant. What is the total amount of water remaining in the watering can?
đổi 40ml = 0,04l
150ml = 0,15l
số nước mà silvia đã dùng là:
0,04 + 0,15 = 0,19 (l)
tổng số nước còn lại trong bình tưới là:
3,48 - 0,19 = 3,29 (l)
vậy tổng số nước còn lại trong bình tưới là 3,29 lít nước
The total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to decrease some item by 4 , then you can subtract 4 from that item to decrease it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How many millilitres are there in one litre?1 litre contains 1000 millilitres.
Given that:
Water in watering can initially = 3.48 litresWater given to cactus plant = 40 millilitresWater given to rose plant = 150 millilitres3.48 litre = [tex]3.48 * 1000 = 3480[/tex] millilitres
Total water given to plants = 40+150 = 190 millilitres
Remaining water in water can = water it initially had - water given to plants = 3480 - 190 = 3290 millilitres
Converting this back to litre:
1000 millilitre = 1 litre
1 millilitre = 1/1000 litres = 0.001 litres
3290 millilitres = [tex]3290 \times 0.001 = 3.29 \: \rm litres[/tex]
Thus, the total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres

What is the y-intercept of the inequality below?
y ≤ ⅖ x-4
Answer:
y > 1/3x - 5
Step-by-step explanation:
First, use the points to find the slope. Use the equation for slope.
Now, you need to find the y-intercept. The y-intercept is the point on the graph that crosses the y-axis. By looking at the graph, the y-intercept seems to be -5.
This gives you 1/3x - 5 for slope-intercept form.
Now, you need to find which equality to use. Because the line is dotted, it cannot be ≤ or ≥. This leaves us with < and >. To choose between the two, you need to test points. Test a point to see if it matches the solution. The point should be on the line but in the shaded area.
I'm gonna pick (0, 0). This point is not on the line, and it is in the shaded region.
y 1/3x - 5
0 1/3(0) - 5
0 0 - 5
0 > -5
The equality > is the correct one. This gives the equality y > 1/3x - 5.

11. 1, 4 -- given; 2, 5 -- definition of angle bisector; 3 -- reflexive property; 6 -- ASA postulate
Step-by-step explanation:
10.The marked angles are supplementary. (The two base angles are congruent, and the exterior angle is supplementary to the unmarked base angle.) That means you have ...
(5x -40)° +(5x)° = 180°
10x -40 = 180 . . . . . . . . . . divide by °, collect terms
x -4 = 18 . . . . . . . . . . . . . divide by 10
x = 22 . . . . . . . . . . . . . add 4
__
11.Normally, the given statements are collected at the beginning of the proof. This one is different. It addresses one angle, the shared side, and then the other angle, before claiming ASA congruence.
Reasons 1, 4: Given
Reasons 2, 5: Definition of angle bisector
Reason 3: Reflexive property of congruence
Reason 6: ASA congruence postulate

Answer:
3.22
Step-by-step explanation:
When adding in the hundreths group, if there isn't another value, it would just be 2. When adding in the tenths, since both .5 and .7 are above the set value you can keep in the tenths group, you have to carry the excess over. .5+.7= 1.2. These steps would all add up to be 3.22. (.52 + 2.0 + .7) = 3.22
