9y – 2 + y= 5y + 10​
RideAnS [48]

Answer:

y=2.4

Step-by-step explanation:

9y-2+y=5y+10

(combine like terms)

10y-2=5y+10

(subtract 5y from both sides)

5y-2=10

(add 2 to both sides)

5y=12

(divide both sides by 5)

y=2.4

I need to know how to solve this and need an explanation along with answer. Thanks!

First you should write what you know since we don't know how many helmets we will use x

helmets - 5(x)
bats - 3(6x)

then write out the equation

5(x)+3(6x)=4600

then solve so first multiple 5 times x and multiply 3 and 6x

5x+18x=4600

then combine like terms which are 5x and 18x

23x=4600

then divide both sides by 23

x=200

200is the number of helmets and since there are six times the bats as helmets you multiply that by six and get

helmets=200
bats=1200

Find the length of<br> __<br> JK<br> Round answer to nearest tenth.
PIT_PIT [208]

Answer:

Step-by-step explanation:

We would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

JK² = JL² + KL² - 2(JL × KL)Cos10

JK² = 61² + 53² - 2(61 × 53)Cos10

JK² = 3721 + 2809 - 6466Cos10

JK² = 6530 - 6367.767

JK² = 162.233

Taking square root of both sides of the equation, it becomes

JK = √162.233

JK = 12.73 to the nearest tenth
