Answer:

2a + 30

Step-by-step explanation:

use the distributive property:

4<em>a</em> + 20- 2<em>a</em> + 10

then rearrange for like terms

4<em>a</em> - 2<em>a</em> + 20 + 10

then add it up

2<em>a </em>+ 30

Answer:

2a + 30

Step-by-step explanation:

break it down so it is 4(a+5)

then work out -2(a-5)

so 4 x a then 4 x 5 which gives 4a + 20

then -2 x a then -2 x -5 which gives -2a + 10

then when you have 4a + 20 -2a + 10

do 4a - 2a which is 2a

do 20 + 10 which is 30

so the answer comes to 2a + 30

if anything doesnt seem right just comment and i will correct

hope this helps :)

Tanzania [10]

Complete Question

We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation

E= 17/20 D

a) How many euros have the same value as 1 U.S. Dollar? euros

b) How many U.S. Dollars have the same value as 1 euro? dollars

Answer:

a) 0.85 euros

b) 1.18 dollars

Step-by-step explanation:

The equation is given as:

E= 17/20 D

a) How many euros have the same value as 1 U.S. Dollar? euros

E = 17/20D

D = 1 dollar

Hence:

E = 17/20 × 1

E = 0.85 euros

b) How many U.S. Dollars have the same value as 1 euro? dollars

E = 17/20D

E = 1 euro

1 = 17/20D

D = 1 ÷ 17/20

D = 1 × 20/17

D = 1.1764705882 dollars

D = 1.18 dollars

In a bag of sweets, 6 are orange and 9 are lime. Jodi chooses a sweet at random, eats it an
Digiron [165]

Answer:\frac{17}{35}

Step-by-step explanation:

Given

The bag contains 6 orange and 9 lime sweets

For both sweets of the same flavor, Jodi must either choose orange or lime

No. of ways it can be done is ^6C_1\times^5C_1+^9C_1\times^8C_1

The total no of ways of selecting two sweets out of 15 is ^{15}C_1\times^{14}C_1

The probability that both sweets are the same flavor

P=\dfrac{^6C_1\times^5C_1+^9C_1\times^8C_1}{^{15}C_1\times^{14}C_1}=\frac{102}{210}=\frac{51}{105}=\frac{17}{35}
