Answer:
Step-by-step explanation:
<em>START:</em> 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ <em>x = - 9</em>
x + 13 = 9 ⇔
x = - 4 ⇔ <em>x = 8</em>
x - 9 = 27 ⇔
x = 36 ⇔ <em>x = 48</em>
9 - 2x = 35 2x = - 35 + 9 ⇔ <em>x = - 13</em>
x + 15 = 17 ⇔
x = 2 ⇔ <em>x = 3</em>
- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ <em>x = - 4</em>
Now is your turn. You can do it!!!
Answer: Number of children = 168
Number of adults = 120
Step-by-step explanation:
Let x = Number of children and y = Number of adults
As per given,
x+y=288 (i)
2.25x+6.80y =1194 (ii)
Multiply 2.25 on both sides in (i)
2.25x+2.25y= 648 (iii)
Eliminate (iii) from (ii)
4.55y=546

Put y= 120 in (i)
x+120=288
⇒ x=288-120
⇒ x= 168
Hence, Number of children = 168
Number of adults = 120

Answer:
it depends. 365.05 or 3.6505×10²
Step-by-step explanation:
In the US, 365.05 is already in standard form.
In the UK, "standard form" is the same as "scientific notation", so the number would be ...
3.6505×10²
Answer:
its A=(-4,2)
Step-by-step explanation:
5/8 and 2/3 so...
8 times 3 is 24 so now put your fraction over twenty four
15/24=5/8
15/24 so fifteen out of twenty fourths of the package is what she has. She takes ten out of the fifteenths because fifteen divided by three is five then multiply by two is ten. Then divide by five and you get two.
15/24. 10-> 15/24 cause... 15 divided by 3 ( from the two thirds she cooked) is 5 then * by 2... 5*2=10
