3x - 7 + 2x - 3 = 90
<=> 5x -10=90
<=> 5x = 100
<=> x=20
ok done. Thank to me :>
What is the solution set of (x - 2)(x - 3) = 2?.
19x+5+16x=180
I need help with this I don’t understand
Hello!
--------------------------------------------------------------------------------------------------------------
19x+5+16x=180
First, add the x's together:
35x+5=180
Now, subtract 5 from both sides:
35x=180-5
35x=175
Divide both sides by 35 to isolate x:
x=5
Hope you find my answer helpful! Please give the crown if you do! (:

A pole is being decorated with 15-meter ribbons that are strung from the top of the 7.2-meter pole to a point on the ground. Which is the approximate measure of the angle formed by the ribbon and the pole?
The angle formed by the ribbon and the pole is 29°
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let θ represent the angle formed by the ribbon and the pole.
Hence:
[tex]sin(\theta)=\frac{7.2}{15} \\\\\theta=sin^{-1}0.48\\\\\theta=29^o[/tex]
The angle formed by the ribbon and the pole is 29°

The proof shows that opposite angles of a parallelogram are congruent. Given: ABCD is a parallelogram with diagonal AC. Prove: ∠ BAD ≅ ∠ DCB What is the missing reason In this partial proof? Question 3 options:
ASA Substution Angle Angle Postulate Alternate Interior Angles are Congruent
A parallelogram is a figure which has its opposite sides to be equal and parallel. The missing reason in the proof is:
B. Substitution Angle Angle Postulate.
A parallelogram is a type of quadrilateral that has its opposite sides to be equal and parallel. The sum of its internal angles is [tex]360^{o}[/tex].
To prove that ∠ BAD ≅ ∠ DCB, we have:
Given parallelogram ABCD;
<BAC ≅ <ACD (alternate angle theorem)
<DAC ≅ <ACB (alternate angle theorem)
<BAC + <DAC = <BAD
Also,
<BCA + <DCA = <BCD
Therefore,
<BAD ≅ <DCB (Substitution Angle Angle Postulate)
Thus, the missing reason in the partial proof is:
option B. Substitution Angle Angle Postulate

3. A dish contains 100 candies. Juan removes candies from the dish each day and no
candies are added to the dish. On day 1, Juan removes 1 candy. On day 2, Juan
removes 2 candies. On each day that follows, Juan removes 1 more candy than he
removed on the previous day. After day n, Juan has removed a total of at least 64
candies. What is the smallest possible value of n?
Please give answers and how to solve it step by step thank you!!!
Answer:
11
Step-by-step explanation:
If i am correct n= the days so with the days adding up day 10 juan would have 55 of the 100 candies, day 11 he would have 66. The statement said at least 64, so it would have to be 64 or the closet amount to 64 but it cannot be lower than 64. So there for 66 is the closest to the given amount, and in order for juan to get 64 he would need to take candies out for 11 days.

Show your solution
Nonsense=acc in brainly will be deleted
Answer:
156.73 cm
Step-by-step explanation:
height of the person = (2.75 × humerus length)+71.48 cm
length of the found humerus = 31cm
∴ height of the person = (2.75 × 31)+71.48 cm
= 85.25 + 71.48 cm
= 156.73 cm

Step-by-step explanation:
let the number to be found be x then
23 [tex]\frac{1}{3}[/tex] % of x = 21 ( change mixed number to improper fraction )
[tex]\frac{\frac{70}{3} }{100}[/tex] x = 21
[tex]\frac{70}{300}[/tex] x = 21 ( multiply both sides by 300 to clear the fraction )
70x = 6300 ( divide both sides by 70 )
x = 90
Then 23 [tex]\frac{1}{3}[/tex] % 0f 90 = 21
