1989 is the fifth studio album by American singer-songwriter Taylor Swift (pictured), released on October 27, 2014. Having been known as a country singer-songwriter, Swift conceived 1989 as a synth-pop record that shifted her sound and image to mainstream pop. She titled the album after her birth year as a symbolic rebirth of her image and artistry. The album's singles included three US Billboard Hot 100 number ones: "Shake It Off", "Blank Space", and "Bad Blood". Critics praised the songwriting for offering emotional engagement that they found uncommon in the mainstream pop scene. The album won the Grammy Award for Album of the Year, and featured in Rolling Stone's 2020 update of their 500 Greatest Albums of All Time. A huge commercial success, 1989 spent 11 weeks atop the US Billboard 200 and has sold over 10 million copies worldwide. (This article is part of a featured topic: 1989 (Taylor Swift album).)
Answer:
she is 13
Step-by-step explanation:
her brother is 7.
13+7=20
The way to do this easily is to first determine the equation for your particular situation. Yesterday she read 75 pages, so that 75 pages is our starting point today, plus 2 pages per minute which is expressed as 2x. So our equation is y=2x + 75. The table with the negative x value...forget it. The two things in math that will NEVER be negative are length/distance and time, so no negative x values allowed. From the first table, after 2 minutes of reading, our equation would be y = 2(2) + 75 and y = 79. So far so good, but let's try another x value just in case. After 14 minutes of reading, our equation is y = 2(14) + 75 and y = 103. Not the y value from the table. So that's not it either. Moving down we go to the third table. After 0 minutes of reading, we KNOW we haven't read 0 pages because yesterday we read 75. So if x = 0, then y has to = 75. So that's not it either. We're running out of possibilities. The last table gives us x = 0 and y = 75, so we already know that's right. After 11 minutes of reading, y = 2(11) + 75 and y = 97. Ok, one more. After 20.25 minutes, y = 2(20.25) + 75 and y = 115.5. The last table is our choice.
