Answer:
a = 6, b = - 12
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms to those on the right side.
a(4x - 10) ← distribute parenthesis
= 4ax - 10a
Compare to 24x + 5b , then
4a = 24 ( divide both sides by 4 )
a = 6
Then
5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )
b = - 12
solve using the quadratic equation 3x^2 -7x -3=0

1. They should leave $3.51 For a tip.
$23.40 x 0.15 = $3.51
The total amount of money they would give is $26.91; 23.40 + 3.51 = 26.91.
2.The Briarwood Middle School chess club has 55 members. 22 of the members are in seventh grade.
To convert a fraction into a percent divide the numerator by the denominator and then multiply that result with 100. We can show this formula by (Numerator/Denominator)*100.
(22/55)*100
= 40.00%
= 40%

Answer:
6 < x < 23.206
Step-by-step explanation:
The smallest that angle CAD can be is 0°. For that, ...
2x - 12 = 0
2x = 12
x = 6
__
The largest angle CAD can be is the angle that corresponds with triangle CAB being isosceles: CA = AB = AD. Then the length of AC satisfies ...
AC·sin(48°/2) = 22/2
On the other side, we have ...
AC·sin((2x-12)/2) = 16/2
This gives us ...
sin(x -6) = 8/11·sin(24°)
x = 6 + arcsin(8/11·sin(24°)) ≈ 23.206
__
The range of values for x is ...
6 < x < 23.206
_____
Additional comment
You may be expected to assume that angle CAD could be as much as 180°. That cannot be the case.

Answer:
A: Not proportional
B: Proportional
Step-by-step explanation:
A: 14/4 = 3.5
40/12 = 0.3333333333333
Therefore A is not proportional
B: 3/9 = 0.3333333333333
15/45 = 0.3333333333333
Therefore B is proportional

At lunch, Marc bought 2 quesadillas and 2 tacos for $10.16, and Jason paid $11.84 for 5 tacos and 1 quesadilla. What was the cost of each taco and quesadilla? Let the cost of a quesadilla be x and the cost of a taco be y.
Answer:
X = 3.39 (Quesadilla) Y= 1.69 (Tacos)
Step-by-step explanation:
You need to do systems of equations.
You take the quesadillas which is X and the Taco is Y and plug them into the equation with the total like this:
2x + 2y = $10.16
x + 5y = $11.84
solve and you get
(3.39, 1.69)
Answer: X = 3.39 (Quesadilla) Y= 1.69 (Tacos)

Now change the size of ΔADE by moving point D to a variety of positions. Check the Show Side Ratios box. What do you observe about the side ratios as you move point D? How do the ratios compare to the ratios that you calculated in part D?
Answer:
Despite changing the length of DE and the size of ΔADE, the ratios of the corresponding pairs of sides remain the same.
Step-by-step explanation:
[tex]\frac{BC}{AB} =\frac{DE}{AD} ,\frac{AC}{AB} =\frac{AE}{AD} , and \frac{BC}{AC} =\frac{DE}{AE}[/tex]

-4a+14+7a-9
will give 88 points in first 10 minutes
Answer:
3a+5
Step-by-step explanation:
add-4a and 7a
3a+14-9
subtract 9 from 14
3a+5
Answer:
[tex] \sf \: 3a + 5[/tex]
Step-by-step explanation:
Given expression,
→ -4a + 14 + 7a - 9
Let's simplify the expression,
→ -4a + 14 + 7a - 9
→ (-4a + 7a) + (14 - 9)
→ (3a) + (5)
→ 3a + 5
Hence, the answer is 3a + 5.
Jenny has 12 marbles.
of these 12 marbles are large.
The rest of these 12 marbles are small.
Each large marble has a weight of 70 grams. Each small marble has a weight of 50 grams.
Work out the total weight of the 12 marbles.
Answer:
720g is your answer friend.
Step-by-step explanation:
The total weight of large marbles = 6×70=420gThe total weight of small marbles = 6×50=300gThe total weight of 12 marbles = 420+300=720gOn a particular day 4% of the students were absent. If there are 1750 students at the school then how many were not absent that day?

1c - 20 = 4 - 3c pls help fast in school rn
Answer:
4c-20= 4
+20 +20
4c= 24
/4 /4
c= 6
Answer:
c = 1 btw can i be brainiest...
Step-by-step explanation:
First, rewrite the left side of the equation and group and combine like terms:
c + (4 − 3c) − 2 = 0
c + 4 − 3c − 2 = 0
−3c + c + 4 − 2 = 0
−3c + 1c + 4 − 2 = 0
(−3 + 1) c + (4 - 2) = 0
−2c + 2 = 0
Next, subtract
2
from each side of the equation to isolate the
c
term while keeping the equation balanced:
−2c + 2 − 2 = 0
−2 − 2c + 0 = −2
−2c = −2
Now, divide each side of the equation by
−2
to solve for
c
while keeping the equation balanced:
−2c - 2 = −2 − 2
−2c − 2 = 1
c = 1
